Investigation of the magnetic properties and magnetic structure parameters of nanocrystalline Fe79Zr10N11 films
The magnetic properties (magnetization curve, ferromagnetic resonance spectrum) of nanocrystalline Fe79Zr10N11 films obtained by RF magnetron sputtering with subsequent annealing were studied experimentally, along with the fundamental magnetic constants of these films (saturation magnetization MS, local magnetic anisotropy energy K, and the exchange coupling constant A). The magnetic properties are discussed within the random magnetic model, which determines the correlation of the magnetic properties with the fundamental magnetic constants and nanostructure parameters (grain size, magnetic anisotropy, and correlation radius RC). The exchange correlation length 2RL for the film magnetic microstructure was determined by correlation magnetometry.
