The geometry dependence of the exchange integrals and the total energies of sulfur-bridged complexes of the types L NiSNiL , L NiS NiL , and 5 5 4 2 4 L NiS NiL is studied by quantum chemical ab initio methods. The linear monobridged 3 3 3 complex is antiferromagnetic, the bi-and triply-bridged com
## Abstract Using a recently developed semiβanalytical method (SelfβConsistent Local RPA or SCβLRPA) 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 c
