N2  - Tb(Fe0.55Co0.45)1.5/Fen and Tb(Fe0.55Co0.45)1.5/(Fe0.5Co0.5n 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 ?0Hc=5 mT and a parallel magnetostrictive susceptibility ??||=d?||/d(?0H)=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. © 2001 American Institute of Physics.
