Abstract
The dielectric properties of (AgI)(1-x)(Ag2MoO4)(x) glasses have been inves tigated at fixed microwave frequency (v = 9.0 GHz) and temperature varying from T = 293 K down to T = 77 K using the usual cylindrical cavity resonati ng in the TM010 mode. The temperature dependence of a.c. conductivity shows the existence of different relaxation processes. The activation energy val ues extracted from the Arrhenius plot of sigma T vs. 1000/T are compared wi th the values obtained from the acoustic attenuation in the same glasses.
