Mn-doped SrTiO(3.0), when synthesized free of impurities, is a paramagnetic insulator with interesting dielectric properties. Since delocalized charge carriers are known to promote ferromagnetism in large number systems via diverse mechanisms, we have looked for the possibility any intrinsic, spontaneous magnetization by simultaneous doping Mn ions and electrons into SrTiO3 oxygen vacancies, thereby forming SrTi(1-x)Mn(x)O(3-δ), extent making doped system metallic. We find an absence enhancement metallic sample compared similarly prepared doped, however, insulating sample. Our results, thus, not agreement recent observation weak system.
