Description

Superconducting properties of Bi2Sr2CaCu2O8 films have been measured using the infra-red spectroscopy technique at fixed frequency. It is possible with this technique to determine the variation of the order parameter as a function of temperature and the critical magnetic field as a function of temperature. This last result together with the BCS theory allows a determination of the Fermi velocity in the a-b plane of the structure. (orig.)
