large finite intercept present in NFL phase is driven to zero in the AFM ordered phase. Nevertheless, the metallic character of the solution is preserved across the transition, as illustrated in the right panel of the same figure by comparing the imaginary parts of the conduction electrons Green’s functions in the two phases. The ordering of the local moments in a Néel state, allows the doped charge carriers to form coherent electronic waves (with doubled wave-vector) and to get delocalized. However, as mentioned above, the AFM state is only stable in a small window of doping and the NFL remains stable for a wide range of parameters.

Magnetic stability {#sec4.3}
------------------

The common wisdom about systems of concentrated impurities described by the PAM is that long-range magnetic ordering is likely to set in, especially if the metallic state is weakened by correlations as in our case.

Our results for the AFM state suggest instead a remarkable stability of the incoherent metallic state as the long-range order is confined to low temperature and small doping concentration.
