Аннотация: The results of the study on the magnetic properties of Fe72.4Ti5.4B19.2O3.0 nanocrystalline films, subjected to annealing in vacuum at 200, 300, and 400◦C, are presented. Films with a mixed (nanocrystalline + amorphous) structure, 0.52 μm thick, were obtained by magnetron deposition on glass substrates. Hysteresis loops were measured using a vibrating magnetometer, and the field and spectral dependences of the transverse Kerr effect (TKE) were determined. Magnetization reversal processes were visualized using a magneto-optical Kerr magnetometer. It was shown that the processes of partial crystallization of the initially amorphous phase and the redistribution of Ti and B within crystalline grains and grain boundaries, leading to the formation of new phases as a result of annealing, manifest themselves in a two-stage magnetization reversal process and in the modification of the TKE spectra.
