Magnetic circular dichroism in x-ray absorption is observed in Fe/Pt m
ultilayers. The magnetization and helicity are both in the plane of th
e Fe/Pt multilayers which are prepared by planar magnetron sputter dep
osition. Lattice and layer pair spacings are measured using grazing in
cidence and high-angle x-ray scattering. The film composition and latt
ice 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 w
ell as the relative thickness of the Fe to Pt layer. The maximum magne
tic moment is measured for a (Fe 9.5 angstrom/Pt 9.5 angstrom)92 multi
layer.
