Abstract

We have been investigating superconductor-normal metal-superconductor (SNS) (Proximity-Effect) Josephson Junctions in which the normal metal is a magnetic heterostructure in which the magnetic character can be actively controlled. As part of this program we have investigated the use of giant magnetoresistive (GMR) Cu-Py multilayers as the barrier in variable thickness planar bridge SNS junctions in addition to in-plane S-GMR contacts. In this paper we report on the latest results from our devices which have been fabricated using our established focussed ion beam (FIB) processes.
