Components of Magnetic Anisotropy of Soft Magnetic Nanocrystalline Fe-Based Films

Abstract:

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 K_ME, magnetostatic K_MS, and surface K_a,S anisotropies are components of experimentally measured effective local anisotropy K_eff. 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.
