Thermal stability of induced magnetic anisotropy (IMA) was studied in a course of subsequent annealings without any load for stress-annealed Fe3Co67Cr3Si15B12 amorphous alloy. Dependence of IMA thermal stability on magnitude of IMA constant, a temperature and exposure of stress-annealing was investigated. the magnetic anisotropy induced at higher temperature is more stable because more long-range order and energy-taking processes take place at these temperatures.
