Contributions of the “soft” (Nd{sub 1-x}Sm{sub x}Dy){sub 2}(FeCo){sub 2}B and “hard” (Nd{sub 1-x}Sm{sub x}Dy){sub 2}(FeCo){sub 14}B magnetic phases to the temperature and field dependences of magnetization and low-frequency magnetic susceptibility of (Nd{sub 1-x}Sm{sub x}Dy)(FeCo)B alloys have been separated. It is established that a small increase in the concentration of Sm within 0.8–3 at % leads to significant variations in the exchange integrals and magnetic anisotropy field of the alloy.
