Abstract |
The static scaling hypothesis for continuous transitions, extended to cases where Tc < 0, has appropriate features to describe heavy fermions. We present here the application of this model to the specific-heat and susceptibility anomalies for the concentrated Kondo system CePd3Bx (x = 0.4 and 1). |

Abstract |
Unit cell volume, magnetic properties and LIII X-ray absorption edge studies in Ce(Pd, M) with M = Ni or Rh show that the Ce demagnetization is mainly driven by volume reduction in Ce(Pd, Ni) and essentially due to the reduction of the d electron number in Ce(Pd, Rh). |

Abstract |
Crystallographic, magnetic and resistivity studies on the Ce-Rh binary phases clearly define two Ce ground state regions : i) CeRh3, CeRh2 and CeRh as intermediate valence compounds and ii) Ce5Rh4, Ce3Rh2 Ce5Rh3 and Ce7Rh3 with magnetic transitions at low temperature. |

Abstract |
The magnetic susceptibility of thirty Ce cubic compounds is analyzed, assuming a temperature dependence of the valence fluctuations. The energy level scheme, obtained by fitting the measured susceptibility is used to calculate other physical properties. A correlation between the Ce ionic radius and the interconfigurational excitation energy has been found. |
