Magnetic x-ray circular dichroism in x-ray absorption has been used to investigate the ternary multilayer system, Fe Co Pt. Samples were prepared by planar magnetron sputter deposition and carefully.characterized, using a variety of techniques such as grazing-incidence and high-angle xray scattering, Auger depth profiling and cross-section transmission electron microscopy. As previously reported, the Fe9.5A Pt9.5A exhibits a large dichroism in the Fe 2p absorption. Interestingly while the
