Abstract

The specific heat anomaly of a polycrystalline sample of BPSCCO (2223 phase) was found to have a peak height δC(T_c)/T_c ≈ 24 mJ/mole K² at T_c ≈ 107 K. The anomaly provides evidence for a fluctuation contribution above T_c, whereas below T_c 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.
