Approximation of the Influence of Effective Magnetic Parameters on the Coercivity of Iron-Based Nanocrystalline Films

The magnetization curves and hysteresis loops of Fe, Fe 90 N 10 , Fe 95 Zr 5 , Fe 85 Zr 5 N 10 , and Fe 77 Zr 7 N 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 materi...

Description
Summary:The magnetization curves and hysteresis loops of Fe, Fe 90 N 10 , Fe 95 Zr 5 , Fe 85 Zr 5 N 10 , and Fe 77 Zr 7 N 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.
