Abstract

Here we present X-ray absorption measurements of a vacuum cleaved Fe0.5Cu0.5Cr2S4 single crystal. Measurements at different positions on the cleaved sample surface clearly reveal a difference between the valence state of the Fe ions in the surface layers and the valency of the Fe ions present in the bulk. These results confirm the findings of recent measurements outlined previously. (C) 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
