The appearance of magnetic moment has been examined on the basis of Anderson Model and d electron Green function, when magnetic dilute alloy has impurity potential with including spin flip term. From the numerical analysis of density of states for d electrons, it is supposed that non magnetic state (i.e. S=0) is stable in comparison with the system with no impurity potential reversing the spins of d electrons. The existence of spin flip term may weaken the magnetic state (S≠0).
