Description
Summary:[Display omitted] •Single-phase samples were prepared by the sol–gel combustion method.•The macroscopic magnetism at room temperature was judged by the magnetization curve and Mössbauer spectrum.•A good thermomagnetic curve was fitted by molecular field theory, and the exact exchange constant was obtained.•The special thermally induced spin behavior of A-site Pr3+ ions are described. 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.
