Varaprasad, Y. Takahashi, K. Hono] L10-ordered FePt nanogranular film is one of the promising candidates for the next-generation high areal density media for heat-assisted magnetic recording (HAMR). To realize a suitable microstructure for the HAMR media, the granular structure composed of uniformly dispersed L10-FePt nanoparticles with various segregants has been optimized using various combinations of segregants and seed layer materials. Although the microstructure of FePt-C came so close to the ideal one for HAMR, it would not be the final answer as the growth of the columnar grain structure is not possible due to too strong phase separation between FePt and C. In this article, we review recent investigations aiming at achieving the ideal microstructure for HAMR media. TMS, 2013 Varaprasad B.
