    • Abstract

       

      The dielectric behaviour of K2SO4-ZnSO4 glasses have been investigated. These glasses exhibit subglassy relaxations close to glass transition temperature. The relative dielectric permittivities exhibit sharp rise nearTg which may be due to loosening of glass constituents leading to ionic dipolar or electrode polarisation contributions.
