AN EQUIVALENT MODEL FOR MICROMAGNETIC SIMULATION OF THE MAGNETIZATION OF FERRIMAGNETIC STRUCTURES

DOI: 10.17804/2410-9908.2024.4.035-046

A model for micromagnetic simulation of the magnetization of a ferrimagnetic film consisting of an alloy of ferromagnetic and rare-earth metals is proposed and discussed. It is shown that the model qualitatively replicates the experimentally observed temperature dependencies of the saturation magnetization of various ferrimagnetic alloys for different percentages of the rare-earth element and that it exhibits a similar magnetic hysteresis loop. The results of the study are of interest for the theoretical analysis of the magnetization behavior of ferromagnetic–heavy-metal film nanostructures, as well as for solving problems of applied materials science and magnetism.

Acknowledgments: The work was supported by the Russian Science Foundation, grant No. 21-72-20160 (https://rscf.ru/en/project/21-72-20160). We appreciate the assistance from the shared research facilities center of the FEFU.

Keywords: ferrimagnetic films, micromagnetic simulation, saturation magnetization, magnetic hysteresis, magnetic anisotropy
