Abstract

The specific heat anomaly of a polycrystalline sample of BPSCCO (2223 phase) was found to have a peak height δC(Tc)/Tc ≈ 24 mJ/mole K2 at Tc ≈ 107 K. The anomaly provides evidence for a fluctuation contribution above Tc, whereas below Tc it is not possible to separate fluctuation and strong-coupling effects. A second, considerably smaller, anomaly appears at T ≈ 101 K when the sample is cooled rapidly from 140 K to 78 K.
