Abstract

UPd2Al3 is a new heavy-fermion superconductor with a recordT c of 2 K. In addition, it shows a transition to long-range antiferromagnetic order atT N =14 K. Its Sommerfeld coefficient is reduced from γ p =210mJ/K2 mole in the paramagnetic to γ0=150mJ/K2 mole in the antiferromagnetic phase.
