N2 - In order to increase the uniaxial magnetocrystalline anisotropy constant (Ku) of a Co50Pt50 film, CoM(M = Pt, Pd, Rh) disordered films are investigated with respect to stacking faults (SFs) in hexagonal-close-packed (hcp) grains. The Co50Rh50 film was revealed to have nearly perfect hcp stacking, while the Co50Pt 50 and Co50Pd50 films contain SFs. Therefore, Pt atoms in the Co50Pt50 films were replaced by Rh atoms to enhance Ku by decreasing the density of SFs. The Co 50(Pt1-rRhr)50 film with r = 0.5 showed a maximum Ku of nearly 1 × 107 erg cm -3, which is around 10 times larger than that for the Co 50Pt50 film.
