Using the surface magneto-optical Kerr effect, we have performed magnetic hysteresis measurements at 300 K on Ag-8-monolayer BccFe-Ag(001) and Cu-7-monolayer FCC CO-Cu(OO1) sandwich structures. Both films magnetically saturate for fields in the region of 100-200Oe applied in the plane of the film. These findings confirm the validity of previously obtained polarised neutron reflection data, from which the absolute value of the magnetic moment per atom had been estimated. In the case of the Fe structure we find evidence of planar shape magnetic anisotropy, whereas for the CO structure we observe an in-plane magneto-crystalline anisotropy and very strong planar shape anisotropy. For each sample, our results are consistent with the existence of both long-range ferromagnetic order and planar interfaces.
