N2 - The atomic structure of single-crystal samples of soft-magnetic Fe–9 at % Ga alloys (the A2-phase region) subjected to thermomagnetic treatment (TMT) is studied by X-ray diffraction. In the course of TMT, the samples in the ferromagnetic state are annealed at 450°C and slowly cooled to room temperature in an external saturating magnetic field. In the alloys subjected to TMT and in the alloys subjected to heat treatment (HT) in zero magnetic field, B2 clusters are found, which are pairs of bcc cells centered with Ga atoms. The TMT and HT are shown to have virtually no effect on the size and volume fraction of B2 clusters in the alloy under study. The formation and stability mechanisms of B2 clusters and their role in the formation of induced magnetic anisotropy in the Fe–Ga alloys are discussed.
