Magnetization reversal in AFC media

Abstract

In this paper, we report on a study of magnetization reversal processes in antiferromagnetically coupled media. We describe the reversal in terms of the reversible and irreversible susceptibility that has been measured for the CoCrPtB system of fixed-recording layer thickness and variable-stabilization layer thickness. We rind that very thin stabilization layers do not couple strongly to the recording layer, and that for Mrt greater than 0.11 memu/cm(2), some of the change in magnetization becomes irreversible.
