В четверг 16 февраля в 16:00 пройдет семинар "Magnetic order control of topological metals and semimetals", докладчик Andrew Boothroyd, University of Oxford, United Kingdom.
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.
