SCIENCE - New kind of magnetism discovered: Experiments demonstrate 'quantum spin liquid'

Following up on earlier theoretical predictions, researchers have now demonstrated experimentally the existence of a fundamentally new kind of magnetic behavior, adding to the two previously known states of magnetism. The experiments demonstrate "quantum spin liquid," which could have applications in new computer memory storage.
