Phase diagram of heavy fermions and valence fluctuators — •Veljko Zlatic — Institut für Festkörperforschung, Forschungszentrum Jülich, 52428 Jülich, Germany

The phase diagram of heavy fermions is obtained by the scaling solution of the periodic Anderson model with the crystal feld split states. The results explain the phase boundaries revealed by pressure and doping experiments on intermetallic compounds with Ce, Yb and Eu ions. A detailed comparison with the pressure experiments on CeRu₂Ge₂, Yb₂Pd₂Sn and doping experiments on EuCu₂(Si_xGe_1−x)₂ is provided as an illustration.
