Abstract

We report the temperature dependence of the electrical resistivity ρ(T) and resultant superconducting B-T phase diagram of CeRhSi3 for fields along the tetragonal c-axis. We have found a bend on the curve of upper-critical-field Bc2(T) vs. temperature. The bend emerges at pressures above 2.4 GPa where the superconducting transition temperature is comparable to or higher than the Néel temperature under zero field. Associated with the emergence of the bend, the ρ(T) curve at each field has an obvious change in the slope at a temperature under the magnetic fields.
