Pyroelectric and dielectric nteasurements have been made on Rb.Cd.(S03).crystals with the simultaneous optical examination of the domain texture of thespecimens. An unusual temperature dependence of the spontaneous polarizationwas found in the ferroelectric phases, which is similar to that found in (NH4)2S04.As the temperature is lowered, the spontaneous polarization appears at theCurie point ( -144'C), gradually decreases and changes its sign below -160'Cwithout an appreciable change at the second transition temperature of -170'C.The reversal in polarization was confirmed to take place by both pyroelectricmeasurement and optical observation. An abrupt change of dielectric constant e.at the Curie point was revealed by using single domain specimens.
