摘要：

Single crystals of Rb2CoBr4were grown by the Bridgman method. DTA and the dielectric constant measurements revealed that the normal-incommensurate transition point T1is 60 °C and the lock-in transition (Curie temperature Tc) is — 81°C (on heating). The temperature dependence of spontaneous polarization Pscoercive field Ecand antiferroelectric polarization PAFwere measured for a single-crystal sample down to liquid nitrogen temperature. © 1990, Taylor & Francis Group, LLC.
