摘要：

A logic gate has been fabricated with the partial use of high-temperature superconducting films and tested to study digital applications of such films. The logic gate consists of three YBa2Cu3O 7-x/Ag/Pb-In superconducting weak links and three inductors. The current-voltage characteristics of the weak links are nonhysteristic. The logic gate successfully provides and and or logic results for two external digital inputs at 4.2 K.
