The crystallographic distortion around chromium and iron has been investigated by use of both theoretical and experimental methods. Through the analysis of the isotropic and dichroic Extended X-ray Absorption Fine Structures at the Cr K-edge, the Cr-O distances have been measured in the distorted chromium coordination shell. Through ab initio molecular dynamics, the distortion of the chromium site has been independently calculated.

Abstract
The crystallographic distortion around chromium and iron has been investigated by use of both theoretical and experimental methods. Through the analysis of the isotropic and dichroic Extended X-ray Absorption Fine Structures at the Cr K-edge, the Cr-O distances have been measured in the distorted chromium coordination shell. Through ab initio molecular dynamics, the distortion of the chromium site has been independently calculated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
