抄録

The intrinsic perpendicular magnetic anisotropy constant Ku for (Fe-Co-Ni)50Pt50 quaternary alloy and (Fe-Cr)50Pt50 alloy thin films is discussed as a function of structure and composition. Both Ms and the estimated Ku values obtained by the extrapolation to order parameter S = 1 using the dependence of Ku on S become maximum at the valence electron number nelect = 8, being independent of alloy system. The magnetic anisotropy is determined to the first approximation by the Fermi energy, which changes with the number of electrons, but not by the band structure itself.
