A simple theory is developed for the interaction of conduction electron spins with local moments in the bulk or at the surface of the metal, with emphasis on the conduction electron system, which is considered most important. When considering a local moment system with a distribution in g ‐values and introducing an interaction strength in the electron system, this can give rise to extra linewidth terms, depending on the coupling strengths between the d‐s, d‐d, and s‐s subsystems, as compared to the width of the g ‐distribution in the d‐system.
