Abstract
The displacements of Fe3+ ions and hence the structures of Fe3+-V-O defects in ABO(3) oxide perovskites are studied by analyzing their electron parama gnetic resonance data from the high-order perturbation formula of zero-fiel d splitting on the basis of the spin-orbit coupling mechanism. The results suggest that the Fell ions in the Fell-V, defect centers are displaced away from the oxygen vacancy V-O by about 0.035 nm. The reasonableness of the d isplacement is discussed.
