Beschreibungen/Notizen

• The present status concerning lower and upper critical magnetic fields, Bc1(T) and Bc2(T), and specific heats, Cs(T), of heavy-fermion superconductors is reviewed. For CeCu2Si2, the data near Tc are found to be in full accord with GL theory. Yet, a surprising enhancement of the elastic mean free path over that in the normal state is inferred. Structure in both Bc1(T) and Bc2(T) of UBe13 appears related to a bump in the normal-state specific heat (B = 0) around T = 0.5 This may be a precursor to the lower of the two calorimetric transitions inU0.97Th0.03Be13 which are confirmed by new Bc1(T)… results.
