Fundamental symmetry breaking and relativistic spin–orbit coupling give rise to fascinating phenomena in quantum materials. Of particular interest are the interfaces between ferromagnets and common s-wave superconductors, where the emergent spin-orbit fields support elusive spin-triplet superconductivity, crucial for superconducting spintronics and topologically-protected Majorana bound states. Here, we report the observation of large magnetoresistances at the interface between a quasi-two…

Interfacial Spin-Orbit Coupling: A Platform for Superconducting Spintronics
Spin-orbit coupling (SOC) is a key interaction in spintronics, allowing an electrical control of spin or magnetization and, vice versa, a magnetic control of electrical current. However, recent
Enhanced spin pumping into superconductors provides evidence for superconducting pure spin currents
TLDR
The results show that the induced spin currents, rather than being suppressed, are substantially larger in the superconducting state compared with the normal state; although further work is required to establish the details of the spin transport process, it is shown that this cannot be mediated by quasiparticles and is most likely a triplet pure spin supercurrent.

This report follows recent developments in the controlled creation of long-range equal-spin triplet supercurrents in ferromagnets and its contribution to spintronics.
Reversible control of spin-polarized supercurrents in ferromagnetic Josephson junctions.
TLDR
It is shown that the use of a barrier comprising three F layers enables full control of the triplet supercurrent and, by using finite element micromagnetic simulations, can directly relate the experimental data to the theoretical models which provide a general framework to understand the role played by magnetic states in long-range supercurrent modulation.
