| Abstract: | The magnetic, optical, and magnetooptical properties of amorphous Gd-Co-Si films of various thickness are investigated. It is shown that the perpendicular component of anisotropy in the films is preserved to very small thicknesses, down to 0.005  m. The character of the thickness dependence of the anisotropy constant is analyzed and compared with the behavior expected according to a simple theoretical model which assumes that the perpendicular anisotropy originates from the microstructure. It is concluded that the probable source of the perpendicular anisotropy in these materials is the anisotropic distribution of atom pairs.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 1, pp. 70–75, January, 1986. |
