Abstract

We report on measurements of the far-infrared reflectivity of an epitaxial, oriented YBa2Cu3O7-δ thin film for radiation with the electric-field vector parallel to the crystal (a, b)-plane and present an analysis that delivers evidence for two different superconducting energy gaps, with 2Δ(0)/kB Tc ≈ 1.9 and ≈ 5.8.
