A Ti-doped sample was prepared in order to show that the Fe4+ fraction can be conveniently monitored. Both results were predicted on the basis of the electronic energy-band scheme of these oxides.5 p.application/pdfeng(c) American Physical Society, 1986Matèria condensadaFísica de l'estat sòlidEstructura electrònicaCondensed matterSolid state physicsElectronic structureEvidence of the anomalous charge state 57Fe4+ in the nuclear decay of 57Co3+info:eu-repo/semantics/article12234info:eu-repo/semantics/openAccess
