QMC COLLOQUIUM
Kagome Metals

David Mandrus
University of Tennessee-Knoxville

Abstract
Metallic kagome lattice materials are emerging as rich systems for exploring the interplay between topology, correlation, and frustrated magnetism. Competing phases and rich phase diagrams are expected in these materials. Here we focus on hexagonal HfFe6Ge6-type“166” compounds, which are a large family of intermetallics related to CoSn. I will discuss magnetism and transport in MMn6Sn6 (M= Y,Sc, and Lu) and also some recent results involving the charge density wave formed in ScV6Sn6. I will also briefly discuss recent progress in developing the capability to perform neutron diffraction under applied electrical current at the Spallation Neutron Source as well as an exciting new family of materials in which magnetic moments can be induced by electrical currents.
