• scattering in superconductor–ferromagnet hybrids is a general phenomenon [32] and full polarization was just assumed for clarity. Therefore, we believe that SCAR is a generic phenomenon that should also be present in superconductor–ferromagnet beam splitters with tunnel contacts [6][63] or chaotic cavities
