Controlling magnetic domain walls with supercurrents
Tim Kokkeler, Risto Ojajärvi, F. Sebastian Bergeret +1
Establishing a versatile, fast and reliable magnetic memory technology is a giant bottleneck for cryogenic computing since present-day room-temperature solutions either cease to wo…

Superconductivity provides a giant enhancement to the spin battery effect
Risto Ojajärvi, Tero T. Heikkilä, P. Virtanen +1
We develop a theory of the spin battery effect in superconductor/ferromagnetic insulator (SC/FI) systems taking into account the magnetic proximity effect. We demonstrate that the…

Clauser-Horne-Shimony-Holt Bell inequality test in an optomechanical device
Juuso Manninen, Muhammad Asjad, Risto Ojajärvi +2
We propose here a scheme, based on the measurement of quadrature phase coherence, aimed at testing the Clauser-Horne-Shimony-Holt Bell inequality in an optomechanical setting. Our…
