|'We're showing that there is a third fundamental state for magnetism.' The experimental work showing the existence of this new state, called a quantum spin liquid (QSL), is reported this week in the journal Nature. Unlike the other two kinds of magnetism, the magnetic orientations of the individual particles within it fluctuate constantly, resembling the constant motion of molecules within a true liquid. There is no static order to the magnetic orientations, known as magnetic moments, within the material, Lee explains. 'But there is a strong interaction between them, and due to quantum effects, they don't lock in place.' The work could possibly lead to advances in data storage or communications, he says--perhaps using an exotic quantum phenomenon called long-range entanglement, in which two widely separated particles can instantaneously influence each other's states.|
