New Material for Spintronics Discovered

Posted by CmdrTaco on from the science-is-cool dept.

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?"

  1. Previous record. by eddy · · Score: 4, Interesting

    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.

  2. 50Ghz processors... by MosesJones · · Score: 5, Interesting


    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.

  3. Remember ferromagnetic memory by panurge · · Score: 4, Interesting
    That was going to revolutionise memory a few years back? But didn't. Remember diamond semiconductors that were going to revolutionise processors, from around 1990? But didn't. Remember GMR heads that were going to revolutionise hard drives? Oops, they did. Didn't fix the slow random access data rate much, but changed the paradigm for backup devices.

    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.

  4. "Not previously available"? Explain please! by Zocalo · · Score: 3, Interesting
    According to the story, the universities have developed a new material for Spintronic devices, something not previously available at room temperatures. What? You mean like IBM's harddrives (from 1997), or the Infineon MRAM it hopes to being to market next year, both of which are mentioned in one of the linked stories. Surely both the harddrive and MRAM consist of "room temperature" devices, albeit most likely of a different material.

    New material. Got that. But what makes it so special?

  5. Don't forget... by StarKruzr · · Score: 3, Interesting

    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.
