Feng, B.H. Li, G. Han, J. Teng, T. Yang, Y. Jiang, G.H. Yu] We have studied the effect of a Bi underlayer on ordering and coercivity Hc of FexPt100-x thin films (atomic content of Fe x=40∼58). We found that the Bi underlayer enhances Hc remarkably. After annealing at 400°C for 20min, a Bi/Fe49Pt51 film can realize an Hc as high as 1.07×103kA/m and a ratio of the remnant Mr to the saturated magnetization Ms as high as 0.93. The ordering process of FePt film was promoted by the diffusion of Bi atoms. Moreover, the Bi underlayer broadens the range of x for high Hc from 49∼55 to 43∼55. Interestingly, with Bi underlayer, the high Hc is affected by x to a less extent. Springer-Verlag, 2007 Feng C.
