Local spin-density theory of interface and surface magnetocrystalline anisotropy: Pd/Co/Pd(001) and Cu/Co/Cu(001) sandwiches
The interface magnetocrystalline anisotropy (MCA) of Cu/Co/Cu(001) and Pd/Co/Pd(001) sandwiches are investigated, employing our recently developed state tracking approach based on the full potential l...

We have grown face-centered cubic (FCC) (111)- and (001)-oriented CoxPd1−x alloy films (x[approximately-equal-to]0.20–0.25) by molecular beam epitaxy on (111)Si and (001)MgO substrates, respectively, with thicknesses [approximately-equal-to]200–1000 Å. 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.
