Title: Spin-polarized superconductivity in semi-super-ferro hybrid nanowires

Recently developed semiconducting InAs nanowires with epitaxial superconducting Al and ferromagnetic insulator EuS shells display induced superconductivity with Zeeman-like splitting at zero external magnetic field [1]. The intricate interplay between spin-orbit coupling, magnetic domains, and superconducting coherence gives rise to unique ground states and corresponding electrical properties. In this talk, I will discuss our latest experiments on spin-polarization of the induced superconductivity [2,3].
