Anotace

V originále

We show that a miltilayer analysis of the infrared c-axis response of RBa2Cu3O7-delta (R=Y,Gd,Eu) provides important new information about the anomalous normal-state properties of underdoped curprate high temperature superconductors. In addition to competing correlations which give rise to a pseudogap that depletes the low-energy electronic states below T*>>Tc, it enables us to identify the onset of a precursor superconducting state below Tons>Tc. We map out the doping phase diagram of Tons which reaches a maximum of 180K at strong underdoping and present magnetic field dependent data which confirm our conclusions.
