Abstract
YBa2Cu3O7 nano-bridges with widths ranging from 200 to 800nm were made using Focused Ion Beam milling. The IV-characteristics of the narrowe st nano-bridges show, under microwave irradiation, pronounced Shapiro steps up to the transition temperature. An inductively shunted single layer SQUID, using these nano-bridges, has been realised by a combinat ion of Focused Ion Beam milling and selective epitaxial growth. Flux t o voltage modulation up to 82K was observed, with a maximum modulation depth of 3.7 mu V at 78K.
