MIT Research Shows New Magnetic State That Could Aid Quantum Computing 49

alphadogg writes "Researchers at MIT and other institutions have demonstrated a new type of magnetism, only the third kind ever found, and it may find its way into future communications, computing and data storage technologies. Working with a tiny crystal of a rare mineral that took 10 months to make, the researchers for the first time have demonstrated a magnetic state called a QSL (quantum spin liquid), according to MIT physics professor Young Lee. He is the lead author of a paper on their findings, which is set to be published in the journal Nature this week (abstract). Theorists had said QSLs might exist, but one had never been demonstrated before. 'We think it's pretty important,' Lee said, adding that he would let his peers be the ultimate judges."

    This isn't "another type of magnetism." + and - attracting is + and - attracting. What they're talking about is a different expression of magnetism, typically because the atoms inside are lined up differently.
    If I remember correctly, type one is all of em pointing the same way. That makes a field that sucks in other oppositely aligned materials.
    Type two has approximately 50% facing one way and 50% the other in a perfectly intermingled way so it has a magnetic field of absolutely nothing in relation to other objects around it.
    This third time is all of the atoms constantly changing magnetic direction and never settle into an order ever. They have a tendency to settle into an order so yeah, not easy to make, lol. Although the atoms themselves aren't moving, cuz it's a solid crystal, so this sort of acts like a perpetual motion device for magnetic fields only, not matter. Kinda neat. But it's still + and - attracting so sorry folks, no new force of physics.

    ...and even then they forget that there is paramagnetism and diamagnetism.

    Let's try to sum up

    • Diamagnetism: the material reacts to a magnetic field by createing a magnetic field in the opposite direction
    • Paramagnetism: the material reacts to a magnetic field by createing a magnetic field in the same direction
    • Ferromagnetism: the magnetic dipoles in the material are ordered and the material produces an intrinsic magnetic field
    • Antiferromagnetism: the magnetic dipoles in the material are ordered counter each other magnetic field
    • What-they-found-magnetism: someone can explain?
