What is it about?
We present quantitative evaluation results of micromagnetic structure parameters of nanocrystalline Fe, Fe95Zr5, Fe90N10, and Fe85Zr5N10 films obtained by magnetron sputtering. It is shown that quantities of magnetocrystalline K1, magnetoelastic KME, magnetostatic KMS, and surface Ka,S anisotropies are components of experimentally measured effective local anisotropy Keff. The shape of the hysteresis loops of the films is determined by the presence of two main macroscopic effective magnetic anisotropies, one of which is the anisotropy field of stochastic domains, and the other is the magnetoelastic anisotropy field due to residual macrostresses.

Why is it important?
Nanocrystalline Fe, Fe95Zr5, Fe90N10, Fe85Zr5N10 and Fe78Zr10N12 films obtained by magnetron sputtering have been investigated. Quantities of magnetocrystalline, magnetoelastic, magnetostatic and surface anisotropies, as components of experimentally measured effective local anisotropy fields of the studied films, have been evaluated. It is shown that the presence of two peaks on the differential susceptibility can be determined by the presence of two magnetic anisotropies, one of which is caused by stochastic domains, and the other is the magnetoelastic anisotropy due to internal macrostresses.
