Abstract
Systematic investigation has been made on CuCl crystals prepared by different methods. The occurrence of different high-pressure phases and various anomalies are found to depend sensitively on the sample conditions. Four-lead electrical measurements showed that all the pressure-induced phases of the thermally equilibrated CuCl crystals studies had positive although small activation energies. A diamagnetic anomaly above 90 K over a temperature range of 10-20 K was observed in the ac magnetic susceptibility of rapidly warmed samples. A sharp increase of electrical conductivity and two extrema of the differential-thermal-analysis signal accompanied the diamagnetic anomaly.Keywords
