Abstract
A comprehensive study of the structure and phase composition, magnetostrictive and magnetic properties of the (Sm0.5R0.5)Fe2 (R = Gd, Tb) compounds was performed. The effect of partial replacement of samarium by gadolinium and terbium on the microstructure of the surface, the temperature of phase transitions, the magnitude of magnetostrictive deformations and magnetization was studied. Using atomic force and magnetic force microscopy, the surface topology at the micro and nanoscale was established, and information on the magnetic domain structure at room temperature was obtained.
