Abstract

We studied the evolution of superconductivity (sc) and antiferromagnetism (afm) in the heavy fermion compound CePt₃Si with hydrostatic pressure. We present a pressure-temperature phase diagram established by electrical transport measurements. Pressure shifts the superconducting transition temperature, T_c, to lower temperatures. Antiferromagnetism is suppressed at a critical pressure P_c ~ 0.5 GPa.

Keywords: CePt₃Si; Superconductivity; Antiferromagnetism; Hydrostatic pressure
