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.

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.
