Abstract

Superconducting microbridges of hard superconductors can be realized reproducibly using an ion bombardment technique. The micromachining is obtained directly by focussing onto the superconducting film a reduced ionic image which represents the structure to be machined. We describe and discuss the superconducting properties of niobium Josephson microbridges fabricated using this technique : critical temperature, normal resistance, I-V characteristic, dc magnetic field effect and microwave field effect. Microbridges with an operating temperature of 4.2 K have been realized.
