Abstract (in Japanese) (See Japanese page) 
(in English) Effects of Ge addition into Co sputtered film on uniaxial magnetocrystalline anisotropy energy (Ku) were investigated. Through the quantitative evaluation of degree of stacking faults using laboratory-scale in-plane XRD, it was found that; ? c-plane-oriented pseudo-hcp structure was formed in CoGe alloy films sputtered on Ru underlayer in the Ge composition less than 21 at.%. ? Saturation magnetization was monotonously decreased with increasing Ge content, while Ku took the maximum value of 6.3×106 erg/cm3 at Ge content of 10 at%. ? -A-B-C-stacking probability, Pfcc, showed 10% for pure Co film, while, 1% for Co90Ge10 film. ? Ge addition was found to eliminate stacking faults in Co-based magnetic grains, which was one reason of the enhancement of Ku for CoGe alloy films.
