Abstract
We have studied the structure and oxygen incorporation in YBa2Cu3O7-de lta thin films during in situ formation by pulsed laser deposition. A quenching technique has been used for the first time to freeze the nat ure of in situ films immediately on termination of growth. In situ res istance and transition-temperature measurements, and x-ray diffraction studies on undoped and Ag-doped films, have shown that an oxygen-defi cient orthorhombic phase is indeed possible during growth due to the p resence of atomic and ionized oxygen species in the laser-induced plas ma.
