The aim is to investigate topological magnetic textures and the anomalous Hall effect in MnRhP, a room-temperature ferromagnet.
Conducted single-crystal magnetization measurements
Performed powder neutron diffraction
Utilized Lorentz transmission electron microscopy for skyrmion observation
Executed first-principles calculations to analyze electronic states.
Confirmed stable magnetic skyrmions above room temperature
Observed significant enhancement of both ordinary and anomalous Hall effects upon cooling
Calculated Berry curvature matches experimentally observed anomalous Hall conductivity, indicating intrinsic mechanisms.
