Abstract
Measurements of the dielectric permittivity are reported for a solid s olution of antiferroelectric betaine phosphate(0.15) and ferroelectric betaine phosphite(0.85) at frequencies 20 Hz < nu < 1 MHz. The freezi ng phenomena in PB0.15BPI0.85 reveal the characteristics of a transiti on into a dipolar glass state. The activation energy was found to be E (b) = 525 K and an external bias field lowers this value to 513 K.
