摘要：

Contributions of the "soft" (Nd1-x Sm (x) Dy)(2)(FeCo)(2)B and "hard" (Nd1-x Sm (x) Dy)(2)(FeCo)(14)B magnetic phases to the temperature and field dependences of magnetization and low-frequency magnetic susceptibility of (Nd1-x Sm (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.
