摘要：

The copper monophosphate compound, alpha-AgCuPO4, was prepared by the conventional solid-state reaction. The purity of the compound was checked by X-ray diffraction technique (XRD). Detailed dielectric and electrical properties of the compound were analyzed as a function of frequency (209 Hz-1 MHz) and temperature (343-514 K). The AC conductivity has been fitted and studied using Jonscher's equation, whose exponent n varied with the temperature, showing that the overlapping large polaron tunneling model (OLPT) is the appropriate model to describe the electrical conduction mechanism.
