Please join us for a CME Seminar presented by Assistant Professor Minhyea Lee from the University of Colorado Boulder as she shares her research on "Topological Hall effect and multiple magnetic states in the A-phase of Fe doped MnSi."  

Abstract

The discovery of a crystalline structure of  non-collinear and non-coplanar spin arrangements – the so-called Skyrmion  lattice – in the A-phase of MnSi  provides a new route to manipulate electrical properties via spin degrees of freedom. The topological Hall effect in the A-phase is  directly connected  to the gauge field emerging from this non-trivial spin texture. In this talk, I will present our electrical transport studies  in Fe-doped MnSi, particularly focusing  on understanding the role of Fe impurities and the magnetic anisotropy of the A-phase.
