摘要：

Measurements of the temperature dependence of the infrared conductivity of the CuO2 planes in YBa2Cu3O7 in the superconducting state are reported. Remarkably, we find that the temperature dependence of sigma-1(omega, T) is independent of omega for omega less-than-or-approximately 500 cm-1, and that it is the same as that of the nuclear Korringa product, 1/T1T. These observations indicate that for the best-characterized high-temperature superconductor, YBa2Cu3O7, the phenomenology of dynamic properties is fundamentally different from that of conventional superconductors.
