Abstract

We measured reflectance spectra R(v) of oxygen deficient Y1Ba2Cu3O7-x(YBCO) films of different thickness, with critical temperatures between 85 and 87 K. Measurements were made at room temperature between 15 and 25000 cm-1. The measured R(v) have a maximum below 100 cm-1and then decrease for v → 0. This low frequency behaviour of R(v) can be accounted for by considering a relevant extra-Drude contribution to the far infrared optical conductivity of YBCO. © 1994 Plenum Publishing Corporation.
