The magnetic structure of Fe100–xZrx films (x = 0, 0.6, 1.8, 2.9, and 4.1 ± 0.1 at%), which is characterized by the existence of stochastic domains determined by correlation magnetometry method, is discussed in terms of the random anisotropy model. It is found that two modes of the magnetic anisotropy field of stochastic domains are formed, which differ in the exchange stiffness magnitude and determine the existence of two modes of the coercive field found in the magnetic hysteresis loops.

The magnetization curves and hysteresis loops of Fe, Fe_90N_10, Fe_95Zr_5, Fe_85Zr_5N_10, and Fe_77Zr_7N_16 films were measured for determining coercive field H _c, saturation magnetization M _s, and the rms fluctuation of local magnetic-anisotropy field a ^1/2 H _a of these iron-based materials. A model approximation with empirical second-order polynomial and Pareto chart clearly demonstrates the influence of the grain size, anisotropy field a ^1/2 H _a, and saturation magnetization on the coercive field.
