Abstract
The XPS MnL-spectra of Co2MnSn, a nearly half-metallic ferromagnet (HM F) and Pd2MnSn were investigated. The most drastical feature of the sp ectra observed is the well-defined magnetic splitting of the Mn 2p(3/2 ), 2p(1/2) lines. This gives direct evidence of the existence of well- defined local magnetic moments in Heusler alloys in comparison with ot her itinerant-electron ferromagnets. The calculations of Mn2p XPS spec tra of these materials were carried out using a fully relativistic gen eralization of the one-step model of photoemission and show excellent agreement with experiment.
