| Abstract: | The spin wave stiffness constant is calculated for itenerant electron ferromagnetic transition metal dilute alloys. Calculations are made in the Random Phase Approximation, using the method of effective magnon Hamiltonian. The term in the magnon energy proportional to impurity concentration is calculated by summing up exactly a perturbational series. |
