In this study, DyFe1−xCrxO3 (DFCO) was synthesized by sol-gel and underwent magnetic measurements and analysis. The experimental data were fitted and calculated by a four-sublattice molecular field model. Unlike previous studies, we found that in DyFe1−xCrxO3, the spin of the A-site rare earth ion Dy3+ also changed simultaneously with the spin reorientation of the Fe3+/Cr3+ ions. The effective spin is defined as the projection of the A site’s total spin on the B site’s spin plane, and the curve of temperature changes was obtained after fitt...
