Abstract
The structure of Co epitaxial films deposited on Pt(001) has been investigated with scanning tunnelling microscopy and surface x-ray diffraction. The Co films grow in a layer-by-layer mode up to the highest examined thickness $(\ensuremath{\sim}30\phantom{\rule{0.3em}{0ex}}\mathrm{\AA{}})$. Their crystalline structure is a tetragonal distortion of the bcc structure in pseudomorphic epitaxy with the substrate. It consists of a $\ensuremath{-}1.8%$ in-plane compressive strain and 5.1% out-of-plane tensile strain. A similar pseudomorphic structure is also observed in $\mathrm{Pt}∕\mathrm{Co}∕\mathrm{Pt}(001)$ trilayers. The magnetic properties of the films have been investigated by transverse magneto-optical Kerr effect and magnetic-resonant surface x-ray diffraction. The films exhibit in-plane magnetic anisotropy easy axes within the thickness range of $5--30\phantom{\rule{0.3em}{0ex}}\mathrm{\AA{}}$. The magnetization curves of Co and interfacial Pt are similar, indicating ferromagnetic coupling.
