Fe 2p absorption in magnetic oxides: Quantifying angular-dependent saturation effects

Abstract

INTRODUCTION Saturation effects related to indirect detection of x-ray absorption spectra, like total electron yield (TEY) or fluorescence yield measurements, are of interest for applications of linear and circular dichroism (respectively XMLD and XMCD). XMCD studies on Fe, Co and Ni using the L-edge TEY spectra have shown that saturation can cause errors in excess of 100% on the extracted magnetic moment values [1]. In TEY measurements, the intensity is given by
