Paper Abstract

We present a comprehensive report of time-resolved reflectivity and transmission measurements of the superconducting system PrxY1-xBa2Cu3O7-(delta ). For a fixed photon energy (1.98 eV), varying the Pr content permits optical probing of energy states both above and below the Fermi level where a superconducting gap is expected to occur. We find qualitatively different behavior in the sign, magnitude, and temporal responses as a function of Pr fraction. Our results indicate that a simple two-fluid model interpretation cannot account for the observed response and that the intrinsic band structure of PrxY1-xBa2Cu3O7-(delta ) plays a significant role in the dynamics of these systems.
