Abstract :
We present results for the complex permittivities of several proton glasses of the form M1-x(NZ4)xZ 2AO4, where M=Rb, Z=H or D, and A=As or P. All measurements were made perpendicular to the ferroelectric axis, so no effects of domain wall motion occurred. Phase coexistence was apparent in all species. The phosphate glasses exhibited a much narrower coexistence composition range than the arsenate glasses
