The intrinsic perpendicular magnetic anisotropy constant K_u for (Fe-Co-Ni)₅₀Pt₅₀ quaternary alloy and (Fe-Cr)₅₀Pt₅₀ alloy thin films is discussed as a function of structure and composition. Both M_s and the estimated K_u values obtained by the extrapolation to order parameter S = 1 using the dependence of K_u on S become maximum at the valence electron number n_elect = 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.
