The high efficiency of spin filtering has propelled chiral molecules to the center of attention in molecular spintronics. In conventional ferromagnet/ heavy-metal heterostructures, the spin Hall magnetoresistance has been established as a highly sensitive probe of the interplay between a charge current and magnetization mediated via spin currents. Here, we investigate the chiral-induced spin selectivity effect by probing the impact of the adsorption of chiral molecules on the spin Hall magnetoresistance of a well-characterized device. The change in the magnetoresistive behavior of the device will give insight into the underlying mechanisms at in hybrid chiral molecule/ metal/ ferromagnet multilayer structures.
