The complex perovskite oxide AgNb0.5Ta0.5O3 (ATN) synthesized by solid state reaction
techinique has single phase with monoclinic structure.The scanning electron micro graph of the
sample shows that grains and grain boundary are there but grain size is not definable from there.
The field dependence dielectric response and loss tangent were measured in the temperature range
from 30o C to 430 o C and in the frequency range from 100Hz to 1MHz. An analysis of the
dielectric constant (Ο΅β) and loss tangent (ta
