Abstract

We present results for the reflectivity, R of two bulk crystals of Ba2YCu3O7- which, below the superconducting transition at Tc, show behavior consistent with perfect reflectivity up to an energy of (3-4)kBTc. We interpret the reproducibility and high R values (especially R1/41 below Tc) as indicative of intrinsic behavior in the highly conducting crystal planes probed by the light. Results above Tc show that the charge carriers have an enhanced effective mass and low scattering rate at low frequency and temperature, indicating a strong interaction with some excitation.
