An EPR study of Fe centres in single crystal KTiOAsO (KTA) has been performed at the Q-band frequency. Two Fe 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 Fe 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. [ABSTRACT FROM AUTHOR] |
