The 2p core excited XAS and XMCD spectra of Cr₁₋δTe with several concentrations of δ=0.11-0.33 have been measured. The observed XMCD lineshapes are found to very weakly depend on δ. The experimental results are analyzed in terms of the configuration-interaction picture with consideration of hybridization and electron correlation effects. The calculated result shows that CrTe can be classified into a charge transfer type material and created holes preferably exist in Te 5p orbitals in Cr deficient materials Cr₁₋δTe, which are in consistence with the observed XMCD feature and the reported band structure calculation.
