We present a recently developed magnetization interpretation method based on the analysis of both the semi-log and the linear magnetization derivative responses [1]. We discuss diverse scenarios of soft magnetic materials based on a law of partial magnetizations for magnetic mixtures and on the Langevin-Weiss model. An algorithm is proposed for fitting the physically based model parameters using a deterministic approach [1], [2]. We illustrate the proposed technique through a variety of well-motivated examples covering isotropic/anisotropic and homogeneous/non-homogeneous materials: an isotropic soft ferrite, a nanocrystalline alloy magnetized transverse to its preferred direction, a non-oriented electrical steel, and a highly grain-oriented electrical steel magnetized transverse to the rolling direction. Our method has demonstrated to simplify the analysis of soft magnets enabling an easier and more accurate modeling of anhysteretic magnetization curves.References[1] J. M. Silveyra and J. C.
