摘要：
The heat capacities of (RbCN)1-x(KCN)x (x = 0.20, 0.35, 0.50, 0.63 and 0.75) were measured between 13 and 300 K. Anomalies due to structural phase transitions to the high temperature cubic phase were found in all of them. Lambda anomalies due to cooperative ordering of the CN- dipoles were observed for x = 0.50, 0.63 and 0.75. In addition to these phase transitions, anomalies of relaxational origin were found in the temperature region below 60 K. The molecular motion related to the relaxation was detected by dielectric measurement at audio frequencies. © 1990.
