Abstract

The magnetic properties of a perpendicular magnetic anisotropy film prepared by an electroless plating method was investigated from viewpoints of film composition. The value of saturation magnetization, M//s, of the film decreases (9. 4 emu cm** minus **3), 30. 8 emu cm** minus **3 and 27. 0 emu cm** minus **3) by one atomic percentage codeposition of nickel, rhenium and phosphorus, respectively. The codeposition of nickel and phosphorus decrease the value of the perpendicular anisotropically magnetic field, H//k. Simultaneously, however, for the low-cobalt-content region with high Ni content, the codeposition of rhenium increases H//k while decreasing M//s, making it possible to prepare perpendicular anisotropically magnetic films. Therefore, in the electroless plating method, lower M//s conditions with high Ni content is advantageous for making perpendicular anisotropically magnetic films.
