|Title:||High Dielectric Permittivity in AFe1/2B1/2O3 Nonferroelectric Perovskite Ceramics (A = Ba, Sr, Ca; B= Nb, Ta, Sb)|
|Abstract:||Afel/2B1/203 (A- Ba, Sr, Ca; B-Nb, Ta, Sb) ceramics were synthesized and temperature dependencies of the dielectric permittivity were measured at different frequencies. The experimental data obtained show very high values of the dielectric permittivity in a wide temperature interval that is inherent to so-called high-k materials. The analyses of these data establish a Maxwell-Wagner mechanism as a main source for the phenomenon observed.|
