Magnetic circular dichroism in x-ray absorption is observed in Fe/Pt multilayers. The magnetization and helicity are both in the plane of the Fe/Pt multilayers which are prepared by planar magnetron sputter deposition. Lattice and layer pair spacings are measured using grazing incidence and high-angle x-ray scattering. The film composition and lattice growth are confirmed using Auger depth profiling and cross-section transmission electron microscopy, respectively. The state of the film magnetization is found to be dependent on the layer pair spacing as well as the relative thickness of the Fe to Pt layer. The maximum magnetic moment is measured for a (Fe 9.5 A/Pt 9.5 A)[sub 92] multilayer.
