- Аннотация: The local environment and oxidation state of a Mn impurity in strontium titanate doped with 3% Mn were studied by X-ray absorption fine structure spectroscopy. The effect of the synthesis conditions on the incorporation of the impurity into A and B sites was studied. It was established that Mn ions substituting for Ti are in the Mn4+ oxidation state and are on-center. Mn ions substituting for Sr are in the Mn2+ oxidation state and off-center, and are displaced from the lattice site by 0.32 Å. It is shown that studies of X-ray absorption near-edge structure can be used to determine the ratio of Mn atoms incorporated into A and B sites in the lattice.
