N2 - The spin polarization (P) of alternate monatomic layered (AML) epitaxial [Fe/Co] n superlattices grown on MgO(001) substrates by electron beam (EB) evaporation has been measured by the point contact Andreev reflection (PCAR) method. The intrinsic transport P of 0.60 was obtained for the AML epitaxial [Fe/Co] n superlattice grown at 75 °C, which is comparable to that of half-metallic Heusler alloys measured by PCAR. The AML epitaxial [Fe/Co] n superlattices on MgO(001), which are expected to possess the B2 ordered structure, show the highest spin polarization of metallic Fe-Co alloy films.
