Epitaxial Fe{sub 100{minus}x}Co{sub x}/Ag(001) alloy films: Structure and element-specific magnetic moments from magnetic linear dichroism
- Heinrich-Heine-Universitaet Duesseldorf, Universitaetsstrasse 1, 40225Duesseldorf (Germany)
The structure and element-specific local magnetic moments in Fe{sub 100{minus}x}Co{sub x}/Ag(001) (16{lt}x{lt}70) epitaxial ultrathin alloy films have been determined by photoelectron diffraction (PED) and related magnetic linear dichroism in angle-resolved core-level photoemission, using a laboratory x-ray source. The PED peaks of the Fe and Co 2p core levels for any of the alloy compositions are at emission angles as expected for a bcc lattice. The dichroism increases for the Fe 2p{sub 3/2} core level with increasing x, whereas that of the Co 2p{sub 3/2} dichroism is virtually independent on the alloy composition. The dichroism of both the Fe and the Co core levels scales well with the calculated dependence of the local magnetic moment on the alloy composition rather than with the average saturation magnetization. {copyright} {ital 1998 American Institute of Physics.}
