The electronic structure of nonmagnetic crystals can be classified by complete theories of band topology, reminiscent of a “topological periodic table.” However, such a classification for magnetic materials has so far been elusive, and hence very few magnetic topological materials have been discovered to date. In a new study published in the journal Nature, an international team of researchers has performed the first high-throughput search for magnetic topological materials, finding over 100 new magnetic topological insulators and semimetals.
