Abstract

The dielectric behavior of Y-Ba-Cu-Ox high Tc superconductors is studied for various oxygen concentrations. It is found that the systems under study have a very large dielectric constant and loss which may due to the ac conductivity of charge carriers. The large dielectric constant may lead to the fundamental explanation of the relation between ferroelectricity and superconductivity. These measurements show that the dielectric constant is larger for higher oxygen concentration. This result may be explained on the basis of the hopping probability change as the oxygen concentration changes.
