Abstract
Time-resolved X-ray diffraction (TR-XRD) is employed to investigate the lattice dynamics during thermal transport in FePt/Ag heat assisted magnetic recording (HAMR) media by varying Ag heat sink layer thickness. The x-ray de-convoluted results not only show the possibility to spatiotemporally separate the electron and phonon thermal transport, but also indicate that the thickness mainly has effects on the phonon thermal transport rather than electron diffusion thermal transport.
