Scanningtunneling microscopy and low energy electron diffraction show that highquality fcc Ni(111) films can be prepared on W(110). Thesubsequent coverage of this Ni template by monolayers of Feleads to a Fe/Ni bilayer with striking magnetic properties. TheFe cap layer induces a spin reorientation of the easyaxis of magnetization from in-plane to perpendicular to the film,as checked with the magneto-optic Kerr effect. At higher Fecoverages, an in-plane magnetization of the bilayer is found, whichis proposed to be caused by the fcc to bcctransition in the Fe layer.
