Abstract

EPR and ENDOR studies show that chromium is incorporated in mono crystalline regions of the grains in PbTiO3ceramics as Cr5+ions at Ti4+sites. The local symmetry of the Cr5+impurity is lower than of the host Ti4+site in the crystallite. ESE measurements of the spin-lattice relaxation of the Cr5+centre point to a structural transition at 10 K. © 1986.
