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!
Why does this sound suspiciously like some washing machine technology gone totally mad?

Step 1. Computers will operate at the speed of light in the future.
Step 2. Humans will not have to use computers any more.
Step 3. ????
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!

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.

That we have finally found the limits of Murphys law? If I understand the article, you can store data on subatomic particles with the electrons used as the cable to transmit the information out? So this means each atom stores an Individual bit? And that any computer that operates at a higher data density would be a Quantum computer?
Also that I can store 6*10^23 bits inside a few grams of silicon?

It is sad that I first read the title as sphinctronics. It is even sadder that I immediately started of thinking of electronic devices plugged into your sphincter.

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

There is no hard evidence that the quantity of electrons in one pixel would storage the Library of Congress.
Someone fell for the FUD.
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!

Ahem. I meant Mn-doped.

Core Memory was around a long time ago. It provided non-volatile memory for a computer.
Isn't this just a molecular version of this idea?
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.
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?

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.

It's both a semi-conductor and have sought after magnetic properties. Is it possible that provious materials were one or the other, but never both?

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.
I'll kill myself if you kill yourself first! ;-)
Hey, it's a ones-in-a-lifetime deal!!
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!
I think thousand of gigs of non-volatile memory will be NOT enough for WindowsWhatever to fill out the entire memory. Gates memory
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
Cthulhu for president!
Bow down and worship my disruptive intrusion!!
pleeeeeease?!!!!
It uses less power, too. MRAM is going to revolutionize every aspect of computing... big-horsepower things like PCs, yes, but ESPECIALLY PDAs.
I can't wait.

The new material is said to keep it special abilities at temperatures up to 150 degrees C.

. . . 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!
Alastair Campbell will want a spintronic device, it sounds perfect for his needs. For more on this, see http://www.bbc.co.uk/bbcthree/news/7oclocknews/fea tures/iraq_committee.shtml
That would be "in abstracto"...
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.

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:
"kill -9 31337"

If the swedes now can find out how to keep their powerplants up and running....
10 ?"Hello World" life was simple then
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.
