Anomalous and Topological Hall Effects in Itinerant Magnets

This book presents an investigation of the anomalous and topological Hall effects in some itinerant ferromagnets and helimagnets by measuring Hall effects driven by electrical or heat current.

Provides experimental results on the thermal Hall effect and NernstEttingshausen effect Systematically explains impurity dependence of the anomalous Hall effect caused by skew scattering in Fe Investigates a new topological Hall effect caused by the scalar spin chirality arising from the modulation of spin structure Nominated as an outstanding contribution by the University of Tokyo's Applied Physics Department as their best thesis in 2012
