Chirality-induced spin selectivity (CISS) and Magnetism Induced by Proximity of Adsorbed Chiral molecules (MIPAC) effects are phenomena that caught significant interests over the last few decades because of the large spin polarizations generated by organic molecules and the alteration of the surface's magnetism upon the adsorption of chiral molecules respectively [1,2]. On the other hand, magnetic skyrmions have emerged as a promising path for next-generation information storage and processing technologies. Thus, tuning skyrmion properties is of increasing interest for application in future spintronic devices. In light of the CISS and MIPAC effects, the use of chiral molecules might represent an attractive approach to address the challenge of tuning skyrmion properties [3]. In this work, we aim to investigate how adsorbed chiral molecules interact with magnetic skyrmions that are stabilized in [Co/Ni]N ferromagnetic multilayers with PMA. We observe that the adsorbed chiral molecules locally change the magnetic properties of the film, affecting the density of skyrmion nucleation sites.
