Magnetic dichroism in L2,3 emission of Fe, Co, and Ni following energy-dependent excitation with circularly polarized x rays
Abstract
The magnetic dichroism in the L2,3 emission spectra of Fe, Co, and Ni, following excitation with circularly polarized x rays, is found to exhibit a dramatic dependence on excitation energy. The observed changes in sign and intensity of the dichroism spectra are explained by a simple model and are shown to negate the use of x-ray fluorescence yield detection for quantitative dichroism absorption measurements. Multielectron effects are found to be minimized by use of monochromatic threshold excitation. © 1994 The American Physical Society.
