Preparation and characterization of epitxial Co-alloy magnetic thin films on oxide single-crystal substrates

Abstract Co-alloy single-crystal thin films were prepared on SrTiO 3 (1 1 1), LaAlO 3 (0 0 0 1), and Al 2 O 3 (0 0 0 1) substrates. The film structure was studied using X-ray diffraction and high-resolution transmission electron microscopy. It is shown that epitaxial growth of a CoCrPt magnetic layer strongly depends on the substrate and underlayer materials.
