Abstract

The results of measurements of the magnetostriction constant λ S of multilayer Fe/CoNbZr sputtered films are reported, performed at room temperature using the strain-modulated ferromagnetic resonance method. Experimental evidence for an interdiffusion layer in the multilayer with iron layer thickness of 12 nm is demonstrated. The magnetostriction of the total multilayer is determined by the balance in magnetostriction among Fe, CoNbZr and the interdiffusion layer.
