Researchers Discover Room-Temperature Multiferroic Topological Crystal

A research team reported the synthesis of a crystalline material that simultaneously exhibits ferromagnetism, ferroelectricity, ferrotoroidicity and topological electronic states at roughly 300 kelvins. Reported by Quantum Zeitgeist, the work claims coupled spin-orbit-mediated symmetry breaking yields controllable topological surface states and ferroic orders, potentially enabling electrically writable, magnetically readable memory, sensitive multi-physics sensors, and topologically protected quantum devices without cryogenic cooling.
