ABSTRACT
FePt-C nanogranular films are coming close to the actual application
as recording media for the next-generation high-density recording
system, heat-assisted magnetic recording (HAMR). To optimize the
L10-FePt nanogranular structure suitable for high-areal-density
recording, various combinations of segregants and seed layer
materials have been explored. In this chapter, we review recent
investigations aiming at achieving the ideal nanogranular structure
for HAMRmedia.
