Frustrated magnetism is a phenomenon occurring in magnetic materials where competing interactions between magnetic moments, often due to geometric constraints or the nature of the interactions, prevent the simultaneous satisfaction of all pairwise interactions, thereby hindering the formation of a simple, low-energy, long-range ordered state. This academic concept and research field investigates the resulting complex behavior, including the absence of conventional magnetic order at low temperatures, the emergence of highly degenerate ground states, and the formation of exotic phases such as spin liquids or spin glasses. Its significance lies in providing fundamental insights into strongly correlated electron systems, exploring novel states of matter, and offering potential relevance for quantum computing and other advanced technologies.
