Description

The dependence of the specific heat of YBa2Cu 3O7-δ on temperature (T) and magnetic field (H) shows a number of features predicted for d -wave pairing: a T2 term for H=0 and an H1/2T term for H≠0 and low T , with a crossover to a stronger T dependence at higher T . For all H and T , these results are consistent with a recently proposed scaling relation. Values of the parameters derived from experimental data agree with theoretical predictions. copyright 1999 The American Physical Society
