摘要：
A systematic investigation of the magnetic properties of Tb-Co amorphous films prepared using radio-frequency ion sputtering in a uniform magnetic field has been carried out. The main regularities of the change in the magnetic anisotropy parameters as a function of the composition (8–43 at % Tb), measurement temperature (5–350 K), and annealing temperature (up to 200°C) have been established. It has been shown that their interpretation can be performed within the framework of the model that takes into account the fluctuating local magnetic anisotropy of the terbium ions, columnar microstructure, and anisotropy of elastic stresses.
