Magnetostriction of an amorphous (Fe82B18)0.9La 5Tb5 alloy

E. Du Tremolet de Lacheisserie , A. Chamberod

The thermal variations of the spontaneous and forced magnetostriction of an amorphous (Fe82B18)0.9La5Tb 5 alloy are given. The room temperature magnetostriction is one order of magnitude smaller than the predicted value, which disproves the potential interest of this alloy as a magnetostrictive transducer. The thermal variation of λs is well described by the one-ion model for ferrimagnets.
