Anotace

V originále

With the technique of infrared ellipsometry we performed a detailed study of the temperature- and doping dependence of the c-axis response of a series of YBa2Cu3O7-delta single crystals. In particular, we explored the anomalous electronic properties at temperatures above the macroscopic superconducting transition temperature, Tc, whose conflicting explanations range from a precursor superconducting state to electronic correlations that compete with superconductivity. We show that the c-axis spectra provide evidence that both kinds of correlations are present and that their contributions can be disentangled based on an analysis with a so-called multilayer model.
