Proton glass behaviour in a solid solution of -irradiated betaine phosphate0.15 betaine phosphite0.85

Measurements of the dielectric permittivity are reported for a solid solution of antiferroelectric betaine phosphate and ferroelectric betaine phosphite at frequencies . The freezing phenomena in reveal the characteristics of a transition into a dipolar glass state. The activation energy was found to be K and an external bias field lowers this value to 513 K.
