Magnetic impurities and itinerant carriers in doped SrTiO3:: Anomalous Hall resistivity

We studied perovskite SrTiO3 into which magnetic impurities (Cr or V) and itinerant carriers (electrons in the Ti 3d band) are introduced. We found that the itinerancy of the electrons on the magnetic impurities and magnetic properties of the compounds depend on the species of the transition metal as impurities. Anomalous Hall resistivity was observed in Cr-doped SrTiO3, and it was found that its coefficient is inversely proportional to the number of itinerant carriers.
