We have investigated the presence of a phase separation in the phase diagram of a Kondo-like spin-hole coupled model. Within a mean-field analysis we find that the system in the normal phase separates into a spin liquid and a Fermi liquid phase. The introduction of a superconducting order parameter stabilizes the system strongly reducing the phase separation region. A reasonable behaviour of T(c) vs. doping delta is also obtained.

Abstract
We have investigated the presence of a phase separation in the phase diagram of a Kondo-like spin-hole coupled model. Within a mean-field analysis we find that the system in the normal phase separates into a spin liquid and a Fermi liquid phase. The introduction of a superconducting order parameter stabilizes the system strongly reducing the phase separation region. A reasonable behaviour of T(c) vs. doping delta is also obtained.File in questo prodotto:
