We perform low-temperature magneto-conductance measurements on Cu and Au thin films with adsorbed chiral molecules investigate their phase-coherent transport properties. Upon adsorption of molecules, the spin–orbit coupling strength in decreases become ferromagnetic as evident from weak localization antilocalization data. A theoretical model indicates that anisotropy molecular tilt angles, provided act magnetic moments, induces a nonvanishing exchange interaction, causing changes Au. Our work adds new viewpoint to plethora unique phenomena emerging molecule materials.
