Pressure-induced electrical and magnetic properties in CeAs, CeSb and CeBi

Abstract

Electrical resistance of single-crystalline CeAs, CeSb, and CeBi has been measured under hydrostatic pressure. In CeAs and CeSb, pressure enhances the change of overall features in the resistance-temperature R(T) curves. Resistance anomalies associated with magnetic phase transitions are observed and are found to be sensitive to pressure. It is noted that the R(T) curve of CeAs at ∼3 GPa is similar to that of CeSb at ambient pressure.
