Abstract

Spin-resolved tunneling in the structure metal-EuS-metal has been obtained. The metal electrodes used in our experiments being non-magnetic, polarization of the tunnel current is attributed to the conduction band splitting in EuS below its ferromagnetic Curie temperature. Enhanced Zeeman splitting in the superconducting aluminum film is also observed.
