[Tb(Fe 0.55 Co 0.45 ) 1.5 /Fe] n and [Tb(Fe0.55Co0.45)1.5/(Fe0.5Co0.5]n multilayers were fabricated by rf-magnetron sputtering from composite targets. Magnetostriction was measured using an optical deflectometer. The as-deposited films showed a soft magnetic and magnetostrictive character, with a coercive field μ0Hc=5 mT and a parallel magnetostrictive susceptibility χλ∥=dλ∥/d(μ0H)=1.4×10−2 T−1. This magnetostrictive softness was strongly improved by heat treatments: the magnetostrictive susceptibility attains the huge value of 5×10−2 T−1 in applied field of 6 mT. The low-field dependence of the magnetostrictive susceptibility and their technical characters are described in detail.
