Abstract

AbstractSuperconductor-normal metal-superconductor (SNS) high-Tc Josephson junctions have been fabricated on c-oriented YBa2Cu3O7-δ (YBCO) films. Focused ion beam (FIB) nano-structure modification (cutting of the film and local deposition of a metal) was used to form the junction with tungsten barrier. The junctions exhibit resistively shunted junction (RSJ) -like I-V characteristics.
