摘要：

An experimental determination (both direct and indirect) of the characteristics of the magnetic microstructure, namely, the ferromagnetic correlation radius R-f and the rms fluctuation of the mean anisotropy D-1/2<H-a>, is performed for amorphous and nanocrystalline ferromagnets with a random anisotropy characterized by the quantities R-c and (DHa)-H-1/2, respectively. The magnetization curves of amorphous and nanocrystalline ferromagnets are found to exhibit a dependence on H that is caused by the alignment of the magnetizations of individual magnetic blocks with the field.
