Spin-polarized Specular Andreev Reflections in Altermagnets
Spin-polarized Specular Andreev Reflections in Altermagnets
We propose a multi-terminal device consisting of an s-wave superconductor coupled to an altermagnet, to generate highly correlated spin currents via Cooper pair splitting. Remarkably, we find that the correlated spin currents are induced by specular Andreev reflections in the altermagnet, an effect that has up to now been predicted …
