摘要：

The anisotropy of upper critical magnetic fields is remarkably different between UPd2Al3 and UNi2Al3. The low-energy excitations observed in inelastic neutron scattering experiments of UPd2Al3 are suggested to be those associated with nodes of a gap function. The temperature dependence of the magnetic Bragg peak intensity in UNi2Al3 shows coupling between antiferromagnetism and superconductivity.
