Magnetic Susceptibility Tensor of Anisotropic Ferromagnetic Magnetized Media

Using a method analogous to the Smit–Suhl method, we have calculated the magnetic susceptibility tensor of ferromagnetic media with allowance for the magnetocrystalline anisotropy and the anisotropy of the magnetomechanical ratio. An analysis has been carried out of the obtained formulas in the particular cases of an isotropic medium with anisotropic magnetomechanical ratio, crystals with uniaxial magnetocrystalline anisotropy, and composite materials with randomly distributed ferromagnetic inclusions of ellipsoidal shape.
