摘要：

We discuss recent thermal expansion measurements on single crystalline samples of the heavy fermion compounds CeCu6, CeRu2Si2, URu2Si2, UBe13 and UPt3, and compare the results with existing specific heat data. The resulting Grüneisen parameters (G{cyrillic} = αvVm/KC) are anomalously large at low temperatures and vary rapidly with temperature. This implies that a single energy parameter can describe the electron-electron interaction only at very low temperatures. © 1990.
