Abstract

Temperature dependences of magnetization of composite films ((CoFeB+SiO2) with different concentrations of metal alloy x = 45–85 at. % with different micro- and nanostructure at temperatures of 2–400 K in magnetic fields of 5 mT and 5 T were obtained. Hysteresis loops of magnetization of films with different x in magnetic fields up to 5 T at temperatures of 2, 100, 300, and 400 K were obtained. It was shown that films with granular structure are characterized by a wider hysteresis loop and have a stronger dependence of magnetization on temperature compared to films with granular-percolation structure and films with a structure in the form of a metal matrix with dielectric inclusions.
