Magnetic x-ray circular dichroism in Fe Co Pt multilayers
- Lawrence Livermore National Lab., CA (United States)
- California Univ., Davis, CA (United States)
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 x-ray scattering, Auger depth profiling and cross-section transmission electron microscopy. As previously reported, the Fe9.5{Angstrom} Pt9.5{Angstrom} exhibits a large dichroism in the Fe 2p absorption. Interestingly while the Co9.5{Angstrom} Pt9.5{Angstrom} has no measurable dichroism, the Fe4.7{Angstrom} Co4.7{Angstrom} Pt9.5{Angstrom} sample has a dichroism at both the Fe 2p and Co 2p absorption edges. These and other results are compared to slab calculation predictions. Possible explanations are discussed.
