| Abstract: | UPd2Al3 is a new heavy-fermion superconductor with a recordTc of 2 K. In addition, it shows a transition to long-range antiferromagnetic order atTN=14 K. Its Sommerfeld coefficient is reduced from  p=210mJ/K2 mole in the paramagnetic to 0=150mJ/K2 mole in the antiferromagnetic phase. |
