Far-infrared properties of ab-plane oriented YBa2Cu3O7-δ
Abstract
Polycrystalline samples of YBa2Cu3O7-δ with a variety of surface treatments show differences in absolute reflectance and width of phonon lines. Samples that are not polished and are measured immediately after annealing have largely grains with the c axis normal to the surface. Such oriented samples show a gaplike depression of conductivity in the far infrared that sets in below the superconducting transition temperature but no true gap. Phonon …
