• The phase transition points of ferroelectric Rb_2ZnBr_4 were re-examined by the DTA technique. The ferroelectric Curie temperature T_C On heating was determined as -81°C. The incomuensurate-normal transition point T_i is 74°C. The dielectric constants in the a, b and c directions were measured in a temperature range of -150〜120°C covering T_C and T_i. The Curie-Weiss law was found to hold in the ferroelectric a direction above T_C. The temperature- and applied field-dependence of the 60 Hz D-E hysteresis loop were studied in detail. The triple loop observed just below T_C and the anomalous field dependence of the spontaneous polarization show the ferroelectricity in Rb_2ZnBr_4 would be ferrielectricity in reality.
