Pb(Sc~ ~Tal \_,)O~ ceramics have been characterized by dielectric measurements in a wide range of frequencies (10 2-10'; Hz). A strong dispersion occurs with two low and high frequency contributions below the transition temperature. Only high frequency relaxation is still observed at high temperatur
In the present work the e4ects of cation ordering on dielectric properties were isolated by investigating three polymorphs of Ca(Ca 1/ 3 Nb 2/ 3 )O 3 that feature di4erent arrangements of the Ca 2ุ and Nb 5ุ cations on the B-sites of the perovskite structure. Dielectric measurements at frequencies a
