For decades, scientists have been searching for quantum spin liquids (QSLs) – materials thought to possess several special properties that could advance our understanding of magnetism and efforts to develop quantum computers . In a new study, a material previously thought to be a QSL has turned out to be something else. The discovery suggests we need to rethink how we evaluate QSL candidates; it also reveals a brand new, non-quantum state of matter . According to the international team of
