摘要：

The heavy fermion superconductor UPd2Al3 exhibits the unusual combination of an antiferromagnetic phase transition, at T-N = 14.3 K, followed by a superconducting phase transition below 2 K without destruction of the ordered magnetic moment. In the superconducting phase the low-energy magnetic inelastic response is qualitatively of a different form from that above T-c. We review this low-energy response. (C) 1999 Elsevier Science B.V.
