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.
