dc.description.abstractWe present a combined experimental and theoretical work that investigates the magnetic proximity effect at a ferromagnetic-insulator - superconductor (FI-S) interface. The simulation is based on the boundary condition for diffusive quasiclassical Greens functions, that accounts for arbitrarily strong spin-dependent effects and spin-mixing angles. The experimentally found differential conductance of an EuS-Al heterostructure is compared with a theoretical calculation. With the assumption of a uniform spin-mixing angle that depends on the externally applied field, we find good agreement between theory and experiment. The theory depends only on very few parameters, mostly specified by the experimental setup. We determine the effective spin of the interface moments as J≈0.74ℏ.eng
