Quantitative Analysis of Domain Structure and Rapid Search for New Materials for Permanent Magnets

The possibilities of application of known models of domain structure to multiphase alloys are analyzed with the aim to assess the anisotropy constants and to search for magnetically uniaxial highly anisotropic phases. It is shown in what cases and how the standard models of domain structure may be applied to such alloys. Recommendations on the necessary amendments of the model to be applied to multiphase materials are given.
