ComputerWorld (emphasis added by me):
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. Theorists had said QSLs might exist, but one had never been demonstrated before.
