| Results of the study of magnetic properties of nanocomposite samples (CoFeZr)x(CaF2)(100−x) (31 at.% ≤ x ≤ 47 at.%) produced in argon (Ar) and argon with oxygen (Ar with O2) sputtering atmosphere are presented in this paper. The magnetic resonance spectroscopy at room temperature using continuous wave X-band electron spin resonance (ESR) was used for analysis of samples magnetic properties. After analysis it is established that in the case of samples produced in argonsputtering atmosphere the value of g increases with the rise of metal content and for samples produced in argon with oxygen atmosphere the value g decrease with the rise of x. Such a behavior of g(x) is explained by the presence of core-shell structure of NPs represented by ferromagnetic core and antiferromagnetic core that results in quenching of orbital motion of electrons. |
