Abstract

The far-infrared c-axis reflectance of Sr2RuO4 has been measured above and below the 2.5 K superconducting transition temperature of the sample. A plasma edge develops near 70cm−1 as the temperature is lowered, which corresponds to a Drude peak in the real optical conductivity associated with the onset of the coherent motion of the carriers. A gaplike suppression of the frequency-dependent scattering rate at low temperatures indicates that the coherent transport is related to a loss of scattering below 60cm−1. A strong resonance near 9 meV is responsible for the scattering that destroys coherence.
