Tunneling in Magnetic Superconducting Systems.

Abstract

The work described in this report was directed at the study of the interaction between magnetism and superconductivity, a classical problem which is important in establishing a fundamental understanding of both phenomena. This field has attracted increased attention as a consequence of the development of stoichiometric compounds which are superconducting and which contain magnetic ions. The coupling between the conduction electrons and these ions can either be ferromagnetic or antiferromagnetic. The work has had two aspects, the study of thin films of magnetic superconducting compounds using electron tunneling as a tool and the development of techniques for the fabrication of films off the Chevrel phase compounds, which, because of their high critical magnetic fields, are potentially technologically significant materials. The tunneling investigations, in addition to revealing fundamental features of magnetic superconducting materials, have also led to the development of some new techniques for the fabrication of artificiall barrier tunneling junctions and have pointed out unusual possibilities for three-terminal superconducting devices.
