英文摘要	The structure, magnetic and magnetostrictive properties of Sm0.88Nd0.12(Fe1-xCox)(1.93) (0 <= x <= 1.0) alloys have been investigated. The alloys have the cubic MgCu2 structure over the whole composition range and the lattice parameter a decreases with increasing x. For 0 <= x <= 0.2, substitution of Co for Fe slightly increases the saturation magnetization M-s and Curie temperature T-c, while further substitution causes a decrease in both M-s and T-c. The spin reorientation is observed, and a phase diagram for the spin configurations of the Sm0.88Nd0.12(Fe1-xCox)(1.93) system is determined. The spontaneous magnetostriction lambda(111) increases as x is increased, while a monotonic decrease of the saturation magnetostriction lambda(s) with x originates from the increase of lambda(100) with opposite sign to that of lambda(111), which may be caused by the filling of the d band due to Co substitution.
