| Abstract(in English) | CoPt-C, FePt-C and PrCo-C nanocomposite thin films were prepared by a pulsed filtered vacuum arc deposition technique. Vacuum thermal annealing and rapid thermal annealing were performed at various temperatures. The dependence of the magnetic properties on the carbon fraction and annealing temperature was studied. For the film with a particular composition of Fe_43Pt_35C_22, the coercivity and the grain size were observed to increase with increasing annealing temperature, up to a value of 3.5 kOe at an annealing temperature of 650℃, and with a grain size about 10.5 nm. For the sample of (Pr_0.17Co_0.83)_69C_31 annealed at 700℃ for one minute, it showed a large coercivity of 5.2 kOe and a small grain size of 7.8nm. The overall small negative ΔM of this film indicated that virtually all the Pr_0.17Co_0.83 grains were isolated single domain particles with only weak dipolar interactions among them. These results indicated that these nanocomposite thin films would be promising candidates for high-density magnetic recording medium applications. |
