| Abstract: | The dielectric
study of Ba(Zn1/3Nb2/3)O3 has been studied at
low temperature in a frequency range 100 Hz-1 MHz and a temperature range from
145K to room temperature. An analysis of real and imaginary part of dielectric
permittivity, impedance (Z),
conductivity and electric modulus with frequency and temperature is performed,
showing the polydispersive nature of the relaxation time in the sample as
confirmed by the Cole-Cole plot of the dielectric permittivity and impedance.
All these results suggest that the relaxation phenomenon seen in the
configuration has been attributable to the damping of dipole oscillators due to
the application of the external fields. |
