Abstract
An anisotropy study is reported on an ultrathin fccCu(111)/Co(111)/Cu(111) wedge grown on a sapphire substrate by molecular beam epitaxy. Roomtemperature polar and longitudinal magneto-optical Kerr effect (MOKE) measurements were analysed by twodifferent methods to determine the volume and surface contributions to theanisotropy. The values obtained by the `area method' by calculating thedifference in area between the in-plane and perpendicular magnetization curvesand also by simulation of the polar MOKE curves were not in agreement. The`area method' was found to be unreliable for analysing MOKE data. Values ofthe anisotropy obtained by simulation agreed with the expected bulk value forfcc Co of 0.0 MJ m-3 and the surface anisotropy was found to lie in the range0.4-0.5 mJ m-2.
