Abstract
In this work, we present a micromagnetic modeling study on a scheme to enhance medium signal-to-noise ratio in heat assisted magnetic recording. By adding a relatively thin magnetic capping layer on top of FePt-L10 granular thin film, recording performance can be significantly improved, especially at high linear densities, provided the capping layer has significant magnetic moment during recording.
