Abstract
When a magnetostrictive Permalloy film is stressed in the direction of its preferred axis of magnetic orientation, an effective anisotropy is induced in the film causing a change in measured Hk. Magnetoelastic measurements were made on evaporated and plated films 100–4000 Å thick and varying in composition from 70% Ni, 30% Fe to 85% Ni, 15% Fe. Composition was determined by x‐ray fluorescence. It was found that the magnetoelastic coupling constant B = (2/M) (dHk/de) was significantly less for plated than for evaporated films of the same composition. There is evidence of both intercrystallite or internal crystallite slip and film‐to‐substrate slip, but neither is large enough to account for the observed differences.This publication has 5 references indexed in Scilit:
