The growth and electronic behaviour of Sm ultra thin films deposited on a Co(0001) substrate have been studied by Auger spectroscopy, high energy electron diffraction and X-ray photoemission experiments. When the Co substrate is held at room temperature, a quasi two-dimensional growth is observed, whereas at higher substrate temperature (610 K), deposition of Sm leads to the formation of an epitaxial trivalent Sm-Co compound. At room temperature, Sm 3d photoemission spectra show an important time dependence.
