【 摘 要 】

The Meccano of heavy fermion systems is shown with special focus on the ideal case of the CeRu2Si2 series. The nice tools given by the temperature, the pressure, and the magnetic field allow to explore different ground states. Experimentally, the Gruneisen parameter, i.e. the ratio of the thermal expansion by the specific heat is a colored magic number; its temperature, pressure, and magnetic field dependence is a deep disclosure of competing hierarchies and the conversion of this adaptive matter to external responses.
