X-ray absorption spectroscopy of transition-metal doped diluted magnetic semiconductors Zn<SUB>1−x</SUB>M<SUB>x</SUB>O
No full textWe have investigated the electronic structure of Zn<SUB>1−x</SUB>M<SUB>x</SUB>O (M: 3d transition metal) by x-ray absorption spectroscopy. Using configuration-interaction cluster-model analyses, electronic structure parameters have been deduced and their chemical trend is discussed. Results show that the p-d exchange constant Nβ is negative and large in cases of Mn, Fe, and Co, which is consistent with the enhancement of magnetic circular dichroism
