Superconducting spin-electronics

Published on February 15, 2016

Superconductivity and Ferromagnetism were long thought to be opposing states of matter, which are mutually incompatible. Latest research suggests, however, that superconductivity and ferromagnetism can coexist under certain conditions.

This creates the foundations of fundamentally new classes of superconducting spin-electronic devices, which are based on the generation and manipulation of spin-carrying supercurrents. In this video we will introduce the concept of superconducting spin-electronics and illustrate two different strategies to create non-dissipative supercurrents in superconductor-ferromagnet hybrid nanostructures.

Torsten Pietsch is leader of a junior research group at the University of Konstanz. His research focuses on the designing new types of functional, hybrid nanostructures and exploring their physical properties. Currently, he and his colleagues study the interaction of spin- and charge currents with electromagnetic radiation and other degrees of freedom in nanoscopic junctions in order to explore conceptually new electronic devices.

Simon Diesch is working on scanning tunneling spectroscopy and -microscopy on superconductor-ferromagnet proximity systems as a PhD student. The objective of this work is to find experimental evidence for spin-carrying supercurrents in the ferromagnetic film in an S/F sandwich structure.

Marcel Thalmann is a MSc. Student in the Pietsch group, working on the transport dynamics of ferromagnetic Josephson junctions. He analyzes the role of the spin-polarisation, thickness and magnetization state of the ferromagnetic spacer on the current-voltage characteristics of these junctions.
