Consideration of the micromagnetic state of a sample in interpretation of magnetic measurement data

A method is proposed for calculating the magnetization curves taking into account the domain structure of a sample, which, in contrast to the method developed by Néel and other researches, does not use a number of assumptions of the Néel model; i.e., this method is more universal. It allows numerical calculation of the micromagnetic state of a sample within a unified approach and has no limitations on the type of magnet anisotropy.
