THREE DIMENSIONAL ATOM PROBE AND FIELD ION MICROSCOPY ANALYSIS OF Co/Pd MULTILAYERS FOR PERPENDICULAR MEDIA APPLICATIONS

摘要

Perpendicular magnetic recording is being considered as an important candidate for achieving extremely high density magnetic recording with high thermal stability [1]. One set of materials being most widely studied for this application are Co/Pd and Co/Pt multilayer films. These films show high hysteresis loop squareness, high coerciviry and a perpendicular anisotropy, the main contribution to which comes from an interfacial anisotropy term.
