Abstract

Ultrafast spin control plays a pivotal role in condensed matter physics. In this study, we analyzed the macroscopic magnetization of the PrFe0.1Cr0.9O3 system by molecular field model fitting. And the whole process of system spin reorientation is accurately calculated in the fitting process. It is found that, unlike the rare-earth perovskites we have previously studied, PrFe0.1Cr0.9O3 exhibits spin-reversion properties during the reorientation process. This research will lay a theoretical foundation for precise spin control in the future.
