Inhomogeneous Kondo destruction by RKKY correlations
KY Park, I Jang, KS Kim, S Kettemann - Annals of Physics, 2021 - Elsevier
The competition between the indirect exchange interaction (IEC) of magnetic impurities in
metals and the Kondo effect gives rise to a rich quantum phase diagram, the Doniach
Diagram (Doniach, 1977). A Kondo screened phase is separated from a spin ordered phase
when the local exchange coupling J and the concentration of magnetic moments n M are
varied. In disordered metals, both the Kondo temperature and the IEC are widely distributed
due to the scattering of the conduction electrons from the impurity potential. Therefore, it is a …
