Abstract

A unique theoretical model to explain the attractive features of high Tc superconductors and the mechanism for the formation of the Cooper pairs is still missing. Since existing theories lead to considerably different predictions for important parameters of superconducting samples such as the real and imaginary part of the complex conductivity, the field penetration depth, the symmetry of the order parameter or the carrier scattering time, accurate measurements of these quantities by various experimental techniques are indispensable in order to check the validity for the different models.
