摘要：

We have grown face-centered cubic (FCC) (111)- and (001)-oriented CoxPd1-x alloy films (x-0.20-0.25) by molecular beam epitaxy on (111)Si and (001)MgO substrates, respectively, with thicknesses almost-equal-to 200-1000 angstrom. Magnetization (SQUID) measurements show that both (111) and (100) films present a perpendicular easy axis, indicating that a strong magnetic anisotropy overcomes the demagnetizing field favoring the in-plane orientation. We have studied this magnetic anisotropy by combining SQUID and torque measurements. Our experimental results cannot be accounted for by only invoking the magnetocrystalline anisotropy of a disordered solid solution of Co in FCC Pd, and rather indicate an anisotropic distribution of Co in the Pd host.
