Superconductivity in UPdAl has a critical temperature of 2.0K and a critical field around 3T. The critical field does not show anisotropy despite the hexagonal crystal structure.
For heavy-fermion superconductors it is generally believed that the coupling mechanism cannot be phononic in nature. In contrast to many other unconventional superconductors, for UPdAl there actually exists strong experimental evidence (namely from neutron scattering  and tunneling spectroscopy ) that superconductivity is magnetically mediated.
In the first years after the discovery of UPdAl it was actively discussed whether its superconducting state can support a Fulde–Ferrell–Larkin–Ovchinnikov (FFLO) phase, but this suggestion was later refuted.
