Soft X-ray magnetic circular dichroism study of Cr5S6

摘要

We have performed soft X-ray absorption spectroscopy and X-ray magnetic circular dichroism study of chromium sulfide Cr5S6. It is found that the XMCD signals appear above 160 K, but it disappears below 150 K, which is due to ferri-antiferro magnetic phase transition. Configuration interaction cluster model analysis shows that the doped holes by the Cr vacancy are likely to be in the Cr 3d orbitals. (C) 2004 Elsevier B.V. All rights reserved.
