Abstract

The local arrangement of a substitutional Cr³⁺ ion for an Al³⁺ ion in corundum is studied by means of a Fluorescence XAFS method. The large single crystal is used and the removal method of the diffraction peak at various energy is described. The Cr³⁺ ion is coordinated in the nearly same structure as Cr₂O₃.
