Abstract
The influence of Ag doping on both oxygenation and deoxygenation durin g growth of YBa2Cu3O7-x films at 700-degrees-C by pulsed laser deposit ion has been studied. Experiments show that undoped and Ag-doped films grown at 200 mTorr oxygen pressure and quenched immediately after ter mination of growth have a superconducting transition temperature T(c) of 61 and 86 K, respectively. The high T(c) of 86 K obtained with quen ched Ag-doped films is thought to be due to both enhanced oxygen incor poration and reduced deoxygenation associated with Ag doping. These re sults show that Ag-doped YBa2Cu3O7-x films could be crucial for realiz ing devices based on multilayer structures.
