Abstract

PURPOSE:To obtain a magnetostrictive material having high material strength and showing large negative magnetostriction in a low magnetic field, by constituting the magnetostrictive material of Sm, one or more elements among Fe, Ni and Co, and one or more elements among Mo, W, Cr, Nb, Ta, Ti, V, Ru, Rh, Pt, and Ag. CONSTITUTION:A magnetostrictive material consists of Sm, one or more elements (T) among Fe, Ni, and Co and one or more elements (M) among Mo, W, Cr, Nb, Ta, Ti, V, Ru, Rh, Pt and Ag and further contains, if necessary, on or more elements (R) among Dy, Ho, and Yb. It is preferable that the above magnetostrictive material has a composition represented by Sm(MXT1-X)Y or RZSm1-Z(MXT1-X)Y, where the symbols X, Y and Z stand for 0.005-0.5, 1.7-2.1, and 0.05-0.85, respectively. By this method, the magnetostrictive material having high material strength and increased in the amount of magnetostriction in a low magnetic field can be obtained, and further, a magnetostrictive material improved in saturated magnetostriction value, saturation magnetization, relative magnetic permeability, etc., and also a magnetostrictive material reduced in coercive force can be attained.
