New Material for Spintronics Discovered
Cpt_Corelli writes "Researchers at Uppsala University and the Swedish Royal Institute of Technology have discovered a new material with properties suitable for creating spintronic devices at room temperature. Previously this was only believed to be available at very low temperatures. The material is a combination of zinc oxide and manganite. The breakthrough is the cover item of the October issue of Nature Materials. If this new material proves viable for production there is an enormous potential for smaller and faster processors. Could this be the beginning of a new era in processor development?"

I don't get it. Could someone please explain this in plain English? Thanks.
The subatomic part of the atom would store the information, and the electron would act as the bus to carry information in and out of the nuclear subsystem
It's actually a disguised, mobile WoMD!

Step 4. Computers will build robots moving at the speed of light.
Step 5. Robots will enslave the world.
Step 6. Robots will enslave the universe.
Step 7. Profit!
I read that the previous record -- from just a year or so back -- was -101c.
This is apparently huge, if the PR-blitz is to be believed.

Here we come, won't that be great. 10Mfps in Quake4D, milliseconds from start to crash in windows.
But still connected to a low bandwidth connection (2Mbps) to an unreliable network with high contention rates and collisions.
Fast processors ceased to become something to get excited about since about 1999, 90% of people don't need them, 8% need more memory instead, and the final 2% do nuclear and climate simulations, work in industrial modelling, or SFX and animation.

Md-doped means Manganese doped, not Manganite. Manganese is an element, Manganite is a mineral, MnO(OH).

Oh yes, very mature, you were probobally just angry that they posted it first.
But, the LOC is the standard unit for measuring unquantifiably huge amounts of storage since (a) no-one knows exactly how big a LOC is, so they cannot dispute your estimate, and (b) the LOC always gets larger, and thus the estimate of "I can fit N LOCs into that space", where N is an integer between 1 and 100, remains accurate despite the logrithmic nature of storage growth.
I for one have never been able to convert LOCs to bushels, and I have no intention of starting now!

No, it means when the benefits of spintronics have been exploited research will proceed to store information in quarks and whatever lies beneath, data transfer will be instantaneous through some weird particle entanglement. And someone will say "6*10^23 bits inside a few grams of silicon will be enough for everyone", and few years later he will be laughed at.

I hope by the time they make an actual product out of this, the paperless office will have become a reality. Otherwise, I'll have a big problem finding my PC on the desk.
Perhaps this is going to be the one that is going to change the bottleneck in the system from the slow memory to the newly slow processor. And the very slow HDD. And the very slow I/O.
Having made which cynical observation, I wonder what impact this could have on database client server? Keeping the database in memory? Multiway processors? It looks like the only people really able to make use of the technology are going to be at IBM, and possibly Sun.
Panurge has posted for the last time. Thanks for the positive moderations.
Please read the comment on the nature of the LOC unit. Thank you.
By the way, the number of electrons in a gram of phosphorous is about 2e22. Assuming 1 gram of the stuff on an monitor, and a 1600x1200 resolution, that's about 1e16 electrons per pixel, and assuming 1 bit per electron (somewhat beyond the state of today's spintronics, but not unimaginable), that's 1,250,000 Gb of data.
Enough for a few LOCs, I believe.

Well, let's not blame him. He has got a point, only it has no relevance on what I was trying at. I wasn't saying 'the same' because it was original, I was saying it, because of the absurdity on itself, AND that it's said everytime. It's like those jokes or catch-phrases that a group of friends in a pub keep repeating: it's not about the 'pointe' anymore; everyone knows what is going to follow, and has heard it before, but that is just what makes the fun. Ah well, it's wasted on some, I'm sure.
When this story broke recently, there was a rebuttal to this claim which I cannot locate at the moment.
Something regarding each additional bit of data requiring more and more precision to both record and detect, to the point where you quickly lose the ability to store anything more.
sorta like the goatse movie..
I remember reading an article on this technology about 15 years ago. The article said it would hold a few terabytes non-volitile in the size of a sugar-cube (2cm^2).
My immediate reaction was how would this affect programming and OS when the line between memory and storage is disolved. Not sure if the interface to CPU would be as fast as current memory, which means it would just be a storage mechanism.
If it could be used for primary memory, what happens to files and how they are viewed (logistically not physically). Would we need 'virtual' files on a RAM-disk or something more abstract?

heh...as is proven by my sudden 'troll' status. Apparently, irony is wasted on some mods too. The same (also repeated) phrase gets a +3 funny a bit further down the articles. But hey, I MUST be a troll if I make a joke of some stiff ass-tight comment of an anonymous cowards' post, instead of giving it an elaborate response it (doesn't) deserves. Right. Well, I have good hopes some mods with a bit more humor will mod it up as funny again. :-)

Indeed! Your powers of deduction are baffling!! You must search for work at MS; they need people like you to deduce if they are ever gonna have another security issue with their OS!
I'm only guessing, but this material makes "spin" transistors possible, whereas previous room-temp applications has been in other areas.

This article (from feb 2003) mentions that one of the major obstacles is making it work at room temperature which now has been achieved. Apparently this is a huge breakthrough.

Just to be clear, they aren't the first to look at Mn-doped ZnO as a spintronic material - people have been working on this material since the 1990s. Theoretical work by researchers at Tohoku University in Japan and others predicted that Md-doped ZnO could work at room temperature. After which, Others started work investigating the properties, and trying to improve the fabrication of the material to reach ferromagentism at higher temperatures.

Aargh, I've done it again. The worst thing is, my job for the next three years is looking at Mn-doped semiconductors, and I can't even type the damn description properly!
You mean like nothing can go wrong so it won't? Or an infinite number of possible wrongs will go wrong?
I think thousand of gigs of non-volatile memory will be NOT enough for WindowsWhatever to fill out the entire memory. Gates memory
Scientists are now attempting to utilise San Francisco as a massive data storage solution, they expect they can store over 125 gigabytes using this new Spintronic effect.
What they mean is that they have discovered ferromagnetic ordering in semiconductors at room temperature. Translation--"magnetic" behavior in semiconductors at room temperature. MRAM and hard drives all use ferromagnetic conductors or "Magnetic" metals

It uses less power, too. MRAM is going to revolutionize every aspect of computing... big-horsepower things like PCs, yes, but ESPECIALLY PDAs.

. . . or composes their own music on their computer, the vast majority of it sucks.
But the fact that it allows anyone with the desire to get into it without a high "cost" of entry, that's a good thing. Used to be that everyone made their own music (no radio, no records), they didn't need a "professional" to do it for them. Yeah, not everyone was a Padrewski, or whatever, but they did it themselves, and they liked it, by gum. A little more of a do it yourself mentality wouldn't be a bad thing.

It means that in 5 years, Moore's Law will stall out. Industry giants like Intel will refuse to make the huge investment to bring spintronics and other technology to market. Moore's Law will only continue at a crawl, and it will become only a function of heat sink size and weight. Processors 10x faster will only be so because their HSF will be 10x bigger. Prepare for extremely heavy desktop towers that become hot to the touch because the case itself becomes the heat sink.
That is, like, so cool, on how you can spend 1 hour looking up info like that.
Cheers!

"10 Terabytes: Printed collection of the U. S. Library of Congress" --appears to be the public standard estimate for the LOC unit***
1250000(GB/screen)/10000GB = 125/screen (LOC)
1600px * 1200px = 1920000 px
1920000px / 125LOC = 15360 px/LOC ~ 124^2 px
At your estimations that's about 125 LOC's on a screen, it's gonna take a little more than a . to store it. Something more to the tune of 124x124 pixels. Yes I know these numbers have almost no base in reality, just perpetuationg the maddness cause it's fun!

At first glance, I misread that as reading "New Material for Sphincters Discovered".
The obvious comment, which I was (and obviously still am) morally compelled to make was: "Well it's about time! That manned mission to Uranus has been on the drawing board for decades!" or something to that effect.

Ah, sir, I beg to correct you.
You have confused the two basic units of LOC conversion, the "screen" and the "pixel". The theoretical data capacity of 1 pixel was 1.25e6 bytes, so 125LOC/pixel.
Which, as I have said earlier, is within the limits of LOC estimation.

In the eternal struggle between hardware engineers trying to make everything faster, and software engineers trying to make everything slower, the hardware engineers have struck yet another grave blow.
Fortunately, I'm hard at work on a new O(n^2) sort algorithm:
1) Completely randomize list.
2) In order traversal looking for out-of-order entries. If one is found return to step 1.
It's no slower than bubble sort, but it eliminates those pesky "best cases".
I'm also planning an operating system that uses an XML-based executable format, and "network RAM" protocol that uses XSLT to access memory paged over an HTTP connection.
Admittedly, it's a big project. We are going to need lots of volunteers if we want to get there before Longhorn.
Liberty you never use is liberty you lose.
This SciAm article describes three categories of ferromagnetic materials. The first two are ferromagnetic alloys (which are what make up MRAMs and other current ferromagnetic tech), and ferromagnetic semiconductors. This team has discovered the first room-temperature (or higher) ferromagnetic semiconducting material, hence opening the way for spin switching and computing.
I was in the Sun-terminal room atthe comp.sci department of Copenhagen University.
I had to get rid of some rogue perl process I was responsible for, so I wrote something like:

I'd further suggest that Md-doped would mean Mendelevium doped, not Mangenese doped... seeing as Md is mendelevium, not manganese.
If you really want to go that far, were is a fucking verb, not a subject/verb contraction.
Clearly the author has corrected theirself to indicate that indeed, Maryland was in fact too complex a proposition. The correct state for primative doping is Minnesota.
