Title
Pressure evolution of the superconducting-normal metal phase boundary in superconductors containing high T<inf>K</inf>Kondo impurities
The pressure evolution of the superconducting-normal phase boundary is studied in the framework of the Matsuura, Ichinose and Nagaoka (MIN) theory for the Kondo effect in superconductors. The Eliashberg approach is used to obtain the normal and anomalous one-particle propagators of the host superconductor. It is found that in the high TKlimit (i.e., In(TK/Tc0) > 1 limit), the slope of pressure induced change in the Tcof a superconductor containing the impurities is greater than the slope of the pressure induced change in the Tcof the host superconductor, dTc0/dP and that it is possible to have a high TKalloy, normal at zero pressure, go superconducting as the pressure is increased.
