摘要：
The torque curves (TC) of amorphous Tb-Fe films with the thicknesses d=10-80 nm and compositions near room temperature compensation point were experimentally investigated. The films were evaporated by electron-beam method. Unidirectional (exchange) anisotropy revealed in TC hysteresis is detected and explained by the strong chemical inhomogeneities of the films. The Fe inclusions are the characteristic peculiarity of Tb-Fe films. Their dimensions are determined by the preparation technique. The exchange field on Tb ions is estimated by using the temperature dependence of the TC amplitude as 1.1 - 1.3 . 10(6) Oe.
