Abstract
An electrochemical corrosion study of high moment, magnetically soft F eXN (X=metal) thin film head materials is presented. Potentiodynamic a nodic polarization in aqueous 0.5M NaCl and 0.25M Na2SO4 solutions is studied for qualitative and quantitative measures of corrosion charact eristics. The effect of annealing, composition, and a comparison with Permalloy and Fe thin films are also presented. A drastic improvement in corrosion characteristics result in the samples made with N-2 flow rate > 10 sccm.
