Localized to Itinerant Electronic Transition in Perovskite Oxides WHO International Programme on Chemical Safety Titel der Originalausgabe: Linee diInterest in the transition metal oxides with perovskite related structures goes back to the 1950s when the sodium tungsten bronzes NaxWO3 were shown to be metallic [1 ], the system Lal_xSr~MnO3 was found to contain a ferromagnetic conductive phase [2], and La0. sSr0. sCoO3 was reported to be a ferromagnetic metal, but with a peculiar magnetization of 1. 5 #a Co atom [3]. Stoichiometric oxide perovskites have the generic formula AMO3 in which the A
