| Abstract |
| Polycrystalline samples of Ba1K_,DyNbiU0311 (hereafter
BKDN) has been synthesized by conventional high·
temperature solid state reaction technique. Using X-ray
diffraction (XRD) technique, the formation of single phase
orthorhombic structure is confirmed. Detailed studies of
dielectric constant (£) and loss (tan S) as a function of
frequency (400 Hz-1 MHz) and temperature (30°·250°C)
reveal that this compound has low dielectric constant and it
undergoes diffuse phase transition. DC resistivity (p) of
BKDN is also measured in 30°·340°C range at a constant
electric field indicating semiconducting nature at higher
temperatures. |
