Anisotropy model for amorphous ferrimagnetic films

Consideration is being given to the model of uniaxial anisotropy of the form of columnar structure of the film, blind with respect to thickness. Exact expression for the constant of uniaxial anisotropy of the form of columnar structure of the film, blind with respect to thickness, was obtained for the most general case of random values of structure parameters. Satisfactory agreement of calculation and experimental dependences Ku(T) was obtained for Gd-Co-Mo-Ar films
