## Description

- description: 'Stoner‒Wohlfarth model (S‒W model) is used to explain the relationship
    between the external magnetic field and the magnetization reversal of a single
    magnetic domain. However, it is inappropriate for inhomogeneous magnetic films
    or bulk materials, such as granular and defective films, because the magnetization
    reversal of the films is affected by magnetic particles or grains which could
    have a different anisotropy for uniaxial magnetic anisotropy (UMA) of the films.
    In this paper, we propose a model based on the S‒W model to understand the magnetization
    switching behavior of magnetic films with misoriented grains. Our model considers
    the distribution effect of different anisotropies originating from magnetic defects
    or domains against the UMA of a magnetic thin film, and a Gaussian function is
    employed for the probability distribution of tilted anisotropy. Finally, we experimentally
    demonstrate that our model describes the magnetic switching behavior of a granular
    magnetic film (FePt-C) with perpendicular magnetic anisotropy. This study provides
    a new analytical method for the magnetization reversal in magnetic devices. '
