Abstract

An EPR study of Fe3+ centres in single crystal KTiOAsO4 (KTA) has been performed at the Q-band frequency. Two Fe3+ centres have been observed for which all spin-Hamiltonian parameters were calculated. The comparison of the pseudosymmetries obtained from fourth-order constants of the spin-Hamiltonian and from a fourth-order crystal field calculation for the two Ti-octahedra, allowed us to locate one Fe3+ at both Ti sites in KTA. The deviation from cubic symmetry is similar and not very large for the two centres showing that the charge compensation mechanism is not at short distance.
