Temperature Dependence of Spontaneous and Induced Polarization of Betaine Calcium Chloride Dihydrate

Abstract
Betaine calcium chloride dihydrate (BCCD) is ferroelectric at low temperatures. A sequence of eight transition points separates different commensurate and incommensurate phases with complicated dielectric behavior. On BCCD and the deuterated compound dielectric and caloric measurements are performed to establish the temperature dependence of dielectric constants, coercive fields, critical fields, spontaneous polarizations and induced sublattice polarizations. Additional data about crystal growth and characterization are presented.
