The method of slow cooling from melting temperature is used to obtain coarse-grain ingots of (FexCo1 – x)2B with columnar structure. It is shown that at room temperature the configuration of the domain structure of the specimens of (FexCo1 – x)2B corresponds to magnetocrystalline anisotropy (MCA) of different types. Alloys Fe2B, (Fe0.4Co0.6)2B, (Fe0.2Co0.8)2B and Co2B exhibit MCA of the type of a “plane of easy axes.” Alloy (Fe0.92Co0.08)2B has a state with spin-reorientation transition of type “easy axis” – “plane of easy axes”.

Key words

magnetic domain structure microstructure magnetocrystalline anisotropy spin-reorientation transition
