Thermally induced spin control is one of the main directions for future spin devices. In this study, we synthesized single-phase polycrystalline ErFe1-xCrxO3 and combined the magnetization curves and Mössbauer spectra to determine the macroscopic magnetism at room temperature. The magnetization of the system at various temperatures is well simulated by molecular field theory. And it is found that under the DM interaction, not only the B-site ions undergo a reorientation process, but the spins of the A-site ions also change at the same time. The effective spin is defined as the projection of Er3+ on the Fe3+/Cr3+ spin plane, and the whole reorientation process is obtained by fitting. This study will complement the actual process of ErFe1-xCrxO3 spin reorientation and will lay a theoretical foundation for the fabrication of future spin-controlled devices.
