A method of separation of ferrimagnetic and paramagnetic components of magnetic anisotropy from the total anisotropy is developed. From the anisotropy measurement of a specimen in a low field (susceptibility anisotropy) and from measurement in two high fields stronger than the saturation field of the ferrimagnetic fraction present, the following anisotropy components can be calculated: susceptibility anisotropy (field-independent) of the paramagnetic fraction, low-field (susceptibility) anisotropy of the ferrimagnetic fraction and high-field anisotropy of the ferrimagnetic fraction. Errors possibly arising from imperfect saturation of the ferrimagnetic fraction in the field practically available are analysed.
