Abstract: FePt-X (X=C, Ti O2, Ta2 O5) nanocomposite films were deposited on MgOCrRu glass substrates at 350 °C by magnetron cosputtering. The comparison investigations on the magnetic properties and microstructure of FePt-X films with various dopants were conducted. All FePt-X films showed (001) preferred orientation and oxide dopants promoted the formation of magnetically soft fcc FePt phase. With 15 vol % C doping, FePt-C film with columnar grains of 7.5 nm was obtained and the out-of-plane coercivity measured at room temperature was as high as 14.4 kOe. The increase in carbon volume fraction to 20% caused the formation of two-layer structure, whereas for the 20 vol % Ti O2 and Ta2 O5 doping, the columnar structure of the FePt films remained and the corresponding grain sizes were 5 and 10 nm, respectively. Ta2 O5 doping showed better grain isolation than the others. The out-of-plane coercivities of FePt-Ti O2 and FePt- Ta2 O5 films were 7.5 and 8.8 kOe, respectively. © 2009 American Institute of Physics.
