Researchers resolve magnetic structures of different topological semimetals

Topological semimetals are one of the major discoveries in condensed-matter physics in recent years. The magnetic Weyl semimetal, in which the Weyl nodes can be generated and modulated by magnetization, provides an ideal platform for the investigation of the magnetic field-tunable link between Weyl physics and magnetism. But due to the lack of appropriate or high quality specimens, most of the theoretically expected magnetic topological semimetals have not been experimentally confirmed. Therefore, exploration of new magnetic topological semimetals is of great importance.
