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."
