Magnetization Distribution in Single-Crystals of Iron-Silicon Alloys

The magnetization distribution in a single-crystalline silicon iron after quenching in the paramagnetic state and after annealing in the ferromagnetic state has been determined by Mössbauer spectroscopy. The specimens containing 5, 6, and 8 at % of silicon had cubic ({100}〈001〉) and Goss ({011}〈001〉) orientations of crystallographic axes. An original method of calculating the relative fractions of magnetization oriented along the magnetic easy axes, including in the plane of a single-crystal specimen or at an angle to this plane, was proposed. The parameters obtained as a result of discrete approximation of the Mössbauer spectra were used. It is shown that after quenching in the paramagnetic state, the magnetization is oriented approximately equiprobably along the three 〈100〉 axes, while after ferromagnetic annealing it redistributes along the 〈100〉 directions lying in the specimen plane.
