Abstract

The magnetization curves and hysteresis loops of Fe, Fe90N10, Fe95Zr5, Fe85Zr5N10, and Fe77Zr7N16 films were measured for determining coercive field Hc, saturation magnetization Ms, and the rms fluctuation of local magnetic-anisotropy field a1/2Ha 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 a1/2Ha, and saturation magnetization on the coercive field.
