Frustrated magnetism occurs in certain materials where the magnetic interactions between spins cannot align in a way that minimizes energy. This situation arises in complex lattice structures, where competing interactions lead to a state of frustration, preventing the system from settling into a simple magnetic order. In these materials, such as some spin glasses and geometric frustrated magnets, the spins may remain disordered even at low temperatures. This unique behavior can result in interesting phenomena, including quantum fluctuations and topological states, making frustrated magnets a topic of interest in condensed matter physics.
