Abstract :
The dielectric properties of the system AgI-CuI-CsI with four molar ratios namely 90-05-05, 70-15-15, 50-25-25 and 30-35-35 have been measured and the results discussed. The relaxational frequencies have been calculated and the activation energies obtained suggest the conduction to be mainly due to silver ions only. The conduction mechanism has been observed to be due to a hopping mechanism of ions irrespective of the variation in the molar ratio. The electronic conductivity measurement shows the presence of electronic conduction in all the samples
