摘要	Unusual large magnetostrictions as well as anisotropy compensation have been found in quaternary Sm(0.9)Pr(0.1)(Fe(1-x)Co(x))(2). The magnetostriction constants lambda(111) and lambda(100) at room temperature are -4600 X 10(-6) and 5600 X 10(-6), respectively, in Sm(0.9)Pr(0.1)(Fe(0.4)Co(0.6))(2). The fact of \lambda(111)\ approximate to \lambda(100)\ can be understood in terms of the competition of different crystal distortion. The spin reorientation is also observed, which can be understood on the basis of a two-sublattice model. A phase diagram for the spin configurations of Sm(0.9)Pr(0.1)(Fe(1-x)Co(x))(2) (0 less than or equal to x less than or equal to 1.0) is determined by analyzing the results of Mossbauer and magnetization measurements. The giant magnetostriction is ascribed to the combined contribution of large magnetostrictive praseodymium and of the filling of the 3d band due to the Co substitution for Fe.
