The paper presents the results of modelling of rhombohedral magnetostriction for Fe–Ga alloys in the cubic crystal structures. The results are obtained with the help of the theory of density functional. We show that the energy of magnetic crystalline anisotropy is a decreasing function of the small deformation in the concentration range from 3,125 to 25 at.%. Magnetic crystalline anisotropy changes the sign, if the deformation is more than 1% for alloys with Ga 15,625, 21,875 and 25 at.%. Rhombohedral magnetostriction constant agrees well with the experiment results for alloys with Ga concentration at 12,5 – 18,75 at.%.
Keywords: magnetocrystalline anisotropy energy, ab intio calculations, rhobohedral magnetostriction.
