Abstract We developed additional technique of perpendicular magnetic anisotropy (PMA) to half-metallic full-Heusler Co$_2$FeSi (CFS) and Co$_2$MnSi (CMS) alloy thin films. In a case of CFS, stack structures of CFS/MgO showed PMA when thicknes of the CFS layers were less than 1 nm. This anisotropy were confirmed to be originated from CFS/MgO interfaces. In a case of CMS, [CMS/Pd]$_6$ superlattice structures were fabricated using MgO substrates with varoius crystal orientaions. Magnetic anisotropy of the superlattice structures depended on its crystal orientation. In particular, the superlattice structures formed using MgO(111) substrates showed PMA. The magentic anistropy energy density were evaluated quantitatively. These technqiue is effective to form half-metallic ferromagnetic thin films with PMA .
