N2 - We have studied the microstructures and magnetic properties of FePt with various metal oxides, to achieve an ideal media structure on glass substrates for thermally assisted magnetic recording. Unlike FePt-C granular films, FePt-MxOy(M = Ti, Nb, W, Zr, and Al) granular films showed an interconnected in-plane microstructure and low coercivity. However, the usage of Cr2O3 as a segregant leads to very fine columnar granular structure, while there is still room for improvement in coercivity.
