Abstract:
FePt-based perpendicular magnetic recording (PMR) media including an ordering temperature reducing layer between a bottom FePtX magnetic recording layer and a nucleation layer. In one embodiment, an ordering temperature reducing layer of carbon is employed to lower the L10 ordering temperature of a FePtC recording layer.
