Layered perovskite-like oxides LnSr2CuTiO6.5 (Ln = La, Nd, Pr) were prepared, of them, the Pr and Nd compounds were for the first time. Their crystal-chemical characteristics and dielectric properties were studied. The dielectric permeability of the compounds was shown to increase considerably after thermobaric treatment (TBT) due to the effects of temperature and high pressure on the anisotropy of interatomic distances in coordination polyhedra (Ln, Sr)O9, (Cu, Ti)O6, and (Ln, Sr)O12. All the oxides studied have an activation conductivity type. [ABSTRACT FROM AUTHOR] |
