The complex impedance of the Ag 2 ZnP 2 O 7 compound has been investigated in the temperature range 419-557 K and in the frequency range 200 Hz-5 MHz. The Z′ and Z′ versus frequency plots are well fitted to an equivalent circuit model. Dielectric data were analyzed using complex electrical modulus M* for the sample at various temperatures. The modulus plot can be characterized by full width at half-height or in terms of a non-exponential decay function f t ð Þ ¼ exp Àt=t ð Þ b . The frequency dependence of the conductivity is interpreted in terms of Jonscher's law: s w ð Þ ¼ s dc þ Aw n . The conductivity σ dc follows the Arrhenius relation. The near value of activation energies obtained from the analysis of M″, conductivity data, and equivalent circuit confirms that the transport is through ion hopping mechanism dominated by the motion of the Ag + ions in the structure of the investigated material.

The high-temperature form of AgCuPO 4 (i.e., β-AgCuPO 4 ) was obtained by conventional solid-state reaction. The sample was characterized by X-ray powder diffraction, Raman, and electrical impedance spectroscopy. Electrical properties were investigated using impedance measurements in the frequency range from 209 Hz to 1 MHz and the temperature range 603 to 719 K. Z′ and Z″ versus frequency plots were well fitted to an equivalent circuit model. It was found that the data of the ac measurements follow the correlated barrier hopping (CBH) model and the model's parameters were determined.
