D. Kumar et al., SILVER DOPING AND ITS INFLUENCE ON THE OXYGENATION DURING IN-SITU GROWTH OF YBA2CU3O7-X THIN-FILMS, Journal of applied physics, 76(2), 1994, pp. 1349-1351
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.
