Abstract:	FePt-C films with high coercivity, (001) texture, and small grain size were deposited on MgOCrRu /glass substrate by cosputtering FePt and carbon at 350 °C. The out-of-plane coercivity measured at room temperature increased from 9.6 to 15.1 kOe when C concentrations increased from 0% to 15%. Further increasing the C contents to 20% and 25% caused the decrease of coercivity to 13.6 and 11.8 kOe, respectively. With C doping, a two-layer structure of FePt-C films was formed and fcc-phase FePt particles were found. By optimizing the sputtering process, FePt-C (001) film with coercivity higher than 14.4 kOe and columnar FePt grains of 7.5 nm in diameter was obtained, which are suitable for ultrahigh density perpendicular recording. © 2007 American Institute of Physics.
