Valence-bond revival in magnetism

Researchers bring to light fundamental behavior of intricate magnetic states–quantum spin liquids

18-Apr-2019

Magnets are prone to order. Their basic constituents, individual magnetic moments, tend to align at low temperatures, thus forming “frozen” magnetically ordered states. A minority of magnets break this trend and reveal peculiar characteristics that can be paralleled to a never-freezing (quantum) ...
