Abstract
High magnetostrictive amorphous multilayers consisting of Tb-Fe (hard) and Fe-B (soft) bilayers have been grown by dc sputtering, The layers have been found to be magnetically coupled for layer thicknesses betw een 25 and 75 Angstrom. As an effect of the coupling, high magnetostri ction values (around 5x10(-4)) are obtained with low coercive fields ( around 100 Oe). A qualitative magnetic model has been developed to acc ount for the influence of the size and magnetic parameters on the mult ilayer magnetostriction and its saturation field, and the observed mag netization processes.
