|Title:||Studies Of Electrical Resistivity Under Pressure On Superconducting Sn-doped Cecoin5|
|Abstract:||Experiments of electrical resistivity as a function of hydrostatic pressure for single crystals of Sn-doped CeCoIn5 are reported. Due to the subtle Sn-doping, Tc is strongly suppressed from Tc=2.3 K of undoped CeCoIn5 to Tc ∼0.7 K for the reported concentration (x∼0.12). As for pure CeCoIn5, superconductivity (SC) seems to evolve out of a non-Fermi liquid (NFL) normal state just above Tc. A temperature-pressure phase diagram is constructed from our results and compared with the properties of pure CeCoIn5 under pressure. Effects of chemical pressure and/or hybridization tuning associated with Sn-doping are discussed. © 2005 Elsevier B.V. All rights reserved.|
