Electron interaction effects and the spin‐wave stiffness constant of an ordered ferromagnetic binary alloy are studied. A general condition for ferromagnetism is obtained for the system. Within a certain approximation, an explicit expression for the spin‐wave stiffness constant is derived in the limit of very weak ferromagnetism.
