Description

Composite thick films of YBa2Cu3O/sub 7-//sub x/ and silver have been prepared on alumina substrates using a paint-on method. It is found that thick films containing greater than about 10% silver by weight have greatly reduced normal resistivities for T>T/sub c/ (onset) and significantly enhanced T/sub c/ (R = 0) as compared with undoped films processed under identical conditions. These results are interpreted in terms of enhanced grain growth and an improved coupling between grain boundaries because of proximity-induced electron pairing in the silver regions
