摘要：
The efficiency of the magnetic-anisotropy induction in the Fe5Co72Si15B8 amorphous alloy during its thermomechanical treatment and the thermal stability of the anisotropy are shown to depend on the structural state of the alloy. Structural inhomogeneities (microinhomogeneities and preprecipitates) formed in the structure of the amorphous alloy upon annealing at 350-430 degrees C increase both the efficiency of the magnetic-anisotropy induction in the course of subsequent heat treatment at 290 degrees C combined with tensile deformation and the thermal stability of the anisotropy.
