Abstract

Results of a quantitative determination of parameters of the micromagnetic structure of nanocrystalline Fe, Fe95Zr5, Fe90N10, and Fe85Zr5N10 films prepared by magnetron sputtering have been reported. The magnetocrystalline (K 1), magnetoelastic (K ME), magnetostatic (K MS), and surface (K a,s) anisotropy constants have been shown to be components of the effective local anisotropy (K eff) constant determined experimentally. The shape of hysteresis loops is determined by the existence of two main components of macroscopic effective magnetic anisotropy, one of which is caused by local (within a nanograin) magnetic anisotropy averaged over the exchange interaction length, while the other is related to magnetoelastic anisotropy due to residual macrostresses.
