摘要：

Reflectivity measurements, at different fixed frequencies, have been performed on Bi2Sr2CaCu2O8 films as a function of temperature and magnetic field. Analysis of the data provides evidence for an order parameter 2-DELTA(0) congruent-to 3.3k(B)T(c) although the variation of this order parameter with temperature is significantly different from that predicted by the weak-coupling BCS model.
