    A numerical technique has been presented for evaluation of the spin-wave stiffness for random diluted ferromagnets. The developed procedure rests on the coherent nature of low-energy spin waves in disordered systems. The formalism has been applied to Mn-doped GaAs, Ga(As,P) and GaN semiconductors.
