To study the role of the spin of ions in the coupling between ferromagnetism and ferroelectricity in type II multiferroic perovskite, we used the sol-gel method to prepare multiferroic perovskite Er_0.9La_0.1Cr_0.8Fe_0.2O₃(ELCFO), and through Mössbauer spectrum and magnetic testing, the macroscopic magnetic characteristics of ELCFO are explored. According to the thermal magnetic curve, we analyzed the state and change of each ionic spin in the ELCFO system in different temperature ranges. And we also explore how ionic spin causes the coupling between ferroelectricity and ferromagnetism. This paper will provide a theoretical basis for studying multiferroic perovskite and play a guiding role.
