Abstract: The paper presents the results of statistical analysis of magneto-phase contrast images of [CoFeB+SiO$_2$+N$_2$] composite films sputtered in nitrogen atmosphere. The relationship of structural features (distribution of granules by effective size) with the concentration of metallic phase is shown. The data on concentration dependences of the position and width of the ferromagnetic resonance line are presented. Using a mathematical model, the relationship between the structural and magnetic characteristics of the investigated composite films is shown.

Keywords: sputtering of films in nitrogen atmosphere, granular and granular-percolation structure, ferromagnetic resonance, statistical analysis.
