The magnetic properties of tilted media with a film stack structure of [(fcc FePt x nm) or (Fe3 Pt y nm)] FePtMgOFePtMgO 4 nmSi O2 4 nmglass were investigated. The angular dependence of coercivity from the film normal to the in plane exhibits a broad peak in the case of Fe3 Pt; implying the tilt of the easy axis from the film normal. The coercivity of the media with a hard layer decreases by about 50% from its initial value with an increase in Fe3 Pt layer thickness. However; the media with fcc FePt exhibit about a 70% decrease in coercivity for layer thickness up to 3 nm. There is not much change in the α [=4π (dMdH)H= Hc] value (α∼2-3) with an increase in the Fe3 Pt layer thickness. © 2006 American Institute of Physics;
