Title: Aging effects and passivation studies on undoped and Ag-doped YBa[sub 2]Cu[sub 3]O[sub 7[minus]x] laser ablated thin films

Abstract

The authors have examined the chemical stability of undoped and 5 weight percent Ag-doped YBa[sub 2]Cu[sub 3]O[sub 7[minus]x] thin films, both grown in situ by pulsed laser deposition technique. The studies indicate that Ag-doped films are more stable than undoped films. The improved chemical stability of Ag-doped films has been attributed to reduction in the effective area of intergranular regions and the presence of passivating silver clusters around grains. The study has also shown that coating the YBa[sub 2]Cu[sub 3]O[sub 7[minus]x] film surface with noble metals like Ag and Au results in passivation of YBa[sub 2]Cu[sub 3]O[sub 7[minus]x] films.
