| Popis: | We study optical interband absorption spectra of insulator and metallic YBa2Cu3O6+ x films in a wide temperature region which includes the pseudogap and superconducting states. We show that in the pseudogap state a stripe structure appears with polaron-like charge carriers having an antiferromagnetic core. |
