Description

Dielectric properties are reported on polycrystalline cubic ordered-perovskite cuprate Sr2Cu(Re0.69Ca0.31)O6 in the frequency range 10 Hz-100 kHz at temperature from 300 to 500 K. Both the dielectric permittivity and dielectric loss factor are found to be frequency and temperature dependent. The enhanced value of the low frequency dielectric permittivity is associated to ionic polarization and interfacial phenomena. The material is found to possess significantly high dielectric permittivity. The calculated ac conductivity suggests semiconducting behaviour for the Sr2Cu(Re0.69Ca0.31)O6.
