Magnetostrictive characteristics of Fe-Al films formed by ion plating process

Abstract

The crystal structure and magnetostrictive properties of Fe-Al thin films prepared by ion plating process were investigated. Film composition, structure, magnetization and in-plane magnetostriction were obtained by energy dispersive X-ray spectroscopy, X-ray diffraction, vibrating sample magnetometer and cantilever method respectively. The film showed higher magnetostrictive susceptibility and larger magnetostriction at low magnetic fields.
