Mössbauer spectroscopy of creep-annealed soft magnetic amorphous alloys

To produce magnetic anisotropy in amorphous alloys, stress-annealing above the Curie temperature was substituted for the common thermomagnetic treatment. A tilting three-angle Mössbauer method was applied to see the changes of the⁵⁷Fe hyperfine field directions and intensities due to this procedure. The resulting pictures of the domain orientations distribution in the Fe₈₀Cr₂B₁₄Si₄ and Fe₄₀Ni₄₀B₂₀ amorphous alloys are compared with the measured magnetic anisotropies and domain structures.
