Anisotropic Dependence of Superconductivity on Uniaxial Pressure in CeIrIn5

Abstract

We measure the effect of uniaxial pressure on the superconducting transition temperature Tc in CeIrIn5. We find a linear change in Tc with both a-axis and c-axis pressure, with slopes of 56 mK/kbar and -66 mK/kbar, respectively. By comparing results from doping studies and different types of pressure measurements, we separate the influences of hybridization and dimensionality on Tc. We find the true geometric influence, for constant hybridization, is dTc/d(c/a)=44 K.
