Soft X-ray magneto-optical constants at the Fe 2p edge determined by Bragg scattering and Faraday effect

Bragg scattering on a Fe/C multilayer in L-MOKE geometry, using circularly polarised undulator radiation, was exploited to determine the optical constants of ferromagnetic Fe across the Fe 2p absorption edges. An alternative data set was obtained from Faraday experiments on identical samples measured in transmission. Both methods lead to a direct determination of both the refractive and absorptive part of the optical constant. (C) 2002 Elsevier Science B.V. All rights reserved.
