摘要：

Magnetic dichroism in spin- and angle-resolved core-level photoemission is investigated within the relativistic one-step model of photoemission based on multiple-scattering theory. Photoelectron scattering in emission from 3p levels of low-index Fe and Ni surfaces is found to affect intensities, dichroism, and photoelectron spin polarizations considerably, in particular in off-normal emission. In general, the calculated spectra agree well with their experimental counterparts in spectral shape, size of the dichroic signal, and spin polarization. Magnetic circular dichroism in a chiral setup is analyzed theoretically using appropriately defined asymmetries. Further, core-level energy positions and photoemission are compared with those obtained within an atomic model. [S0163-1829(99)10621-0].
