摘要：

We discuss a series of experiments that evidence that most of the heavy-fermion compounds are close to an electronic or magnetic instability. In the approach of the magnetic instability, the volume plays a major role, as follows from a Gruneisen parameter study. We illustrate our viewpoint by a study of the appearance of long-range magnetic order on doping in UPt3 and CeRu2Si2 and, in particular by an extensive study of the metamagnetic-like transition in the latter compound. Finally, we draw attention to the possibility of an unconventional superconducting ground state in the U-based heavy-fermion superconductors.
