Perpendicular Magnetic Recording Meida (FePt-Fe3Pt)/Mgo with Tilted Easy Axis

In this work, magnetic properties and structure of granular type tilted media of (FePt-Fe₃Pt )/MgO are investigated. The reason for choosing Fe₃Pt is because the ordered Fe₃Pt alloy thin films are found to exhibit large magnetic anisotropy (Kl and K2 are -4x10⁶ erg/cc and 2x10⁷ erg/cc) at room temperature, respectively, and thus a composite grain of FePt and Fe₃Pt is expected to tilt the easy axis, leading to a lower coercivity.
