ANOMALOUS PHONONS IN YBa2Cu3O7-δ SUPERCONDUCTOR
-
Abstract
The anomalous phonon properties in YBa2Cu3O7-δ superconductor quenched from different temperatures were obtained by means of IR refiection spectroscopy. The analyses of the data suggest that polarons exist in the system, and this may provide a cruicial clue to the mechanism study.
