摘要: Pyroelectric and dielectric measurements have been made on Rb 2 Cd (SO 4 ) 3 crystals with the simultaneous optical examination of domain texture specimens. An unusual temperature dependence spontaneous polarization was found in ferroelectric phases, which is similar to that (NH SO . As lowered, appears at Curie point (-144^° C ), gradually decreases changes its sign below -160^° without an appreciable change second transition -170^° The reversal confirmed take place by both pyroelectric measurement observation. abrupt constant e b revealed using single
