The samples in the system Gd_1-xBa_xCoO₃ (x = 0.00, 0.10, 0.20) were prepared by chemical route. These samples form single-phase materials, which were confirmed by XRD and TGA studies. The presence of interfacial polarization is responsible for high value of dielectric constant in these materials. The conductivity observed in Gd_1-xBa_xCoO₃ system may be due to mobile holes created by excitation of an electron from the pi* band to an acceptor level.
