Abstract

Gaussian fluctuations have been observed in the specific heat of two single crystals ${YBa}_{2}$ ${Cu}_{3}$ $O_{7 - δ}$ . Deviations from a BCS-type step are well accounted for by 3D Gaussian fluctuations whose amplitude ratio, in the cleaner sample, implies that the number of order-parameter components is 7±2. This result is inconsistent with an O(2) Ginzburg-Landau theory.
