Magnetic order control of topological metals and semimetals

Topological metals and semimetals exhibit exceptional transport behaviour due to the existence of low energy quasiparticles which resemble relativistic fermions. A particular interest is to identify materials in which the topology of the electrons can be controlled by magnetic order or magnetic fields. In this talk, I will discuss how magnetic structures can couple to electronic band topology, drawing examples from very recent studies on several intermetallic compounds, including candidates for Weyl semimetals and axion insulators. I especially wish to highlight the strengths of scattering experiments using advanced synchrotron radiation and neutron techniques for probing important aspects of the magnetic structures.
