本文主要综述了最近几年对重费米子超导体CeCu_2Si_2、UBe_(13)和UPt_3所做的实验研究。着重介绍了重费米子超导体的奇异特性,尤其对与标准的BCS超导理论不符的实验现象和可能的P波配对超导的解释作了较系统的总结,对实验现象之间的一些关联也作了讨论。在理论方面,简要概述了对重费米子的起源、超导机制以及超导态的特性所做的理论研究的主要进展。
This paper reviews the experimental measurements on heavy fermion superconductors CeCu2Si2, UBe13 and UPt3 in recent years. The main aim is to introduce the exotic properties of these superconductors, especially those phenomina unclear so far and inconsistent with the standard BCS theory. The possible interpretations of p-wave pairing of the superconducting electrons for the unusual behaviors are presented. Several correlations between properties are discussed. The principal progress of the theoretical researches on the origin of heavy fermions, the superconducting mechanism and the identifying of the supercorducting state is also briefly outlined.
