Law of approach to magnetic saturation in nanocrystalline and amorphous ferromagnets with improved transition behavior between power-law regimes

Komogortsev, S. V.; Iskhakov, R. S. JOURNAL OF MAGNETISM AND MAGNETIC MATERIALS, 440 213-216; Doi: 10.1016/j.jmmm.2016.12.145 OCT 15 2017.

New law of the approach to magnetic saturation is proposed based on scaling in ferromagnets with random magnetic anisotropy. This law is consistent with the known laws derived within perturbation theory in extreme cases, but it describes the transition mode between the power-low asymptotic regimes better. The improved law is proper for reliable fitting the approach magnetization to saturation in nanocrystalline and amorphous ferromagnets.
