Abstract

A new method to characterize the optical constants of thin films has been applied to YBa2Cu3O7-x epitaxial single crystal thin films Tc=90 K grown on MgO substrates to determine the far-infrared optical conductivity σab(ω) for ω = 50 - 250 cm-1 and T = 34 - 97 K. Analysis of the temperature dependence of the σab(ω) based on the two-fluid model suggests that the symmetry of the superconducting pairing state of the specimen is d-wave.
