Within the past years a new research field around chirality induced spin selectivity (CISS) has emerged and gains increasing attention. The central part is often played by complex chiral or helical molecules; ferromagnetic, gold capped, sometimes structured substrates and electrical transport measurements [1]. An aspect most often forgotten within this framework is the effects static equivalent [2]. We observed the Spin Polarization Induced via the Proximity of Adsorbed Chiral Molecules (SPIPAC) effect in nickel thin films for various chiral molecules. This study probes the resulting magneto-optical signal of the Ni substrate using Circular Dichroism spectroscopy. Furthermore, the impact of film thickness of the substrate, molecule density on the surface and the chirality of the molecules is explored. [1] B. Bloom et al., Chem.
