Dielectric properties of Ba2YMoO6 ceramics
چکیده انگلیسی

Double-perovskite Ba2YMoO6 ceramics were prepared via the solid-state reaction route. Their dielectric properties were investigated as a function of temperature (100 °C≤T≤800 °C) and frequency (300 Hz≤f≤5 MHz). In the temperature below 600 °C, two thermally activated dielectric relaxations can be well identified. The low-temperature relaxation was ascribed to be a dipolar relaxation caused by oxygen vacancy diffusion, and the high-temperature relaxation is found to be a Maxwell–Wagner relaxation due to surface-layer effect.
