Kick-off of the SUPERSPIN project for the development of new frugal electronic devices combining supraconductivity and spintronic

Friday, April 4, 2025 - 21:55

On March 27th and 28th 2025, the IJL hosted the kick-off seminar for the SUPERSPIN project, which was attended by about twenty researchers from the partner laboratories IJL, SPINTEC, LAF, CINAM, LPS and PHELIQS. The SUPERSPIN project (1 M€, 2025-2028), funded by the PEPR-SPIN, aims to combine superconductivity and spintronics to develop new frugal electronic devices by reducing Joule heating and extending the quantum coherence of spin states that carry information. The project is coordinated by Thomas Hauet from the SPIN-101 team at IJL.

Spintronics (spin-based electronics) outperforms electronics in many applications, and provides novel functionality. Further possible improvements include the continued reduction of Joule heating, the enhancement of spin signals, their lifetime, and propagation lengths, as well as new spin detection schemes. SUPERSPIN aims to address these challenges by combining superconductivity and spintronics. In particular, through the generation and propagation of spin-polarized quasi-particles and/or equal spin-triplet Cooper pairs in superconductor-based spintronics devices, we aim to quench Joule heating, and extend the quantum coherence of spin states carrying information. Although the past 15 years have been rich in theoretical predictions, many fundamental and technical issues still hinder the rise of what we shall call superspintronics. SUPERSPIN propose superconducting/magnetic hybrid heterostructures to reliably and efficiently generate spin-polarized quasi-particles or equal spin-triplet Cooper pairs, as well as new techniques to detect and manipulate both spin-polarized quasi-particles and triplet Cooper pairs, down to the nanometer and picosecond scales.
