FePt granular films with grain size smaller than 10 nm are promising candidates for storage media used in the next generation heat-assisted magnetic recording technology. However, FePt films show degraded magnetic properties when the grain size is re

We investigated the microstructure and magnetic properties of FePt-(C,SiO2) granular films deposited on MgO, MgTiO, and MgTiON underlayers. The coercivity and grain size of the FePt-(C,SiO2) film are substantially degraded when deposited on the MgTiO

Heat-assisted magnetic recording (HAMR) is being developed as the next-generation magnetic recording technology. High anisotropy granular media such as FePt-C have been demonstrated as HAMR media for ∼2 Tbpsi (terabits per in2) recording density. I

Adjacent layers of magnetically hard and soft materials are of both fundamental and technological importance, yet systematic experimental studies of how to control the interlayer exchange coupling (IEC), and how the IEC affects the magnetization dyna

Heat-assisted magnetic recording (HAMR) employs a laser to heat the recording medium nearly to its Curie temperature ${T}_{C}$, to ease magnetization switching. HAMR hard drives have been promised for the near future, yet an understanding of magnetic
