Description

Measuring the power release Q after rapid cooling a YBa2Cu3O7 sample (m = 42.85q, Tc = 91K) from the equilibrium temperature T1 (2.35K ≤ T1 ≤ 15.1K) to To = 1.5K, the authors observed a time dependence typical of glasses: Q is proportional to 1/t. The results allow us to determine the linear term of the heat capacity (0.8 mJ/mole · K2) due to the two-level systems. While the low temperature heat capacity anomaly noticable decreases, the power release does not change essentially after the oxygen reduction of the sample
