Pressure dependence of the superconducting transition temperature of MgCNi3

The new superconductor MgCNi3 with a TC∼8 K is an interesting candidate for non-conventional superconductivity as it is in the borderline of ferromagnetism. We have performed a systematic study of several samples of this compound under pressures up to 25 GPa, measuring the electrical resistivity bet...
