Using a recently developed semi‐analytical method (Self‐Consistent Local RPA or SC‐LRPA) we study the stability of the ferromagnetic phase in diluted magnetic systems where the exchange coupling between magnetic impurities are of RKKY form. A short discussion of the relevance of these calculations w...
