Multistep Topological Transitions Among Meron and Skyrmion Crystals in a Centrosymmetric Magnet
摘要
This chapter provides the detailed description of the study on a centrosymmetric magnet. Based on the comprehensive studies with magnetization measurement, electrical transport measurement, neutron scattering and resonant X-ray scattering, the multistep topological transitions among meron and skyrmion crystals are unveiled in a centrosymmetric magnet GdRu2Ge2. This chapter includes both of the detailed experimental analysis and detailed theoretical calculation, which would be useful to the broad readership in the condensed matter physics.
