Polar magneto-optic Kerr effect (MOKE) measurements on epitaxial Cu/22ACo/0-49Å Cu/53Å Ni/Cu/Si(001) structures reveal that the Ni magnetisation is aligned in-plane for zero Cu spacer layer thichness and becomes increasingly aligned out-of plane with increasing Cu spacer layer thickness, whereas an in-plane remanence for Co is always observed. Polarised neutron reflection (PNR) measurements at room temperature yield at room temperature a slightly reduced mangetisation of 1.57±0.08μ_B for Co and 0.50±0.04μ_B for Ni for a Cu/22Å Co/10Å Cu/53Å Ni/Cu/Si(001) structure. PNR measurements yield also a reduced in-plane remanence for both Co and Ni. This could suggest either a canted magnetisation or multidomain state at remanence. The Latter mechanism is supported by magnetic force microscopy images.
