| Research Abstract |
By the low temperature oxidation technique using ozone, we attempted to synthesize new materials containing metallic ions in unusual high valence states such as Fe4+. In Fe4+-oxides, oxygen holes caused by the deep d level in metallic ionsgive rise to the unique properties unlike in Fe2+- and Fe3+-oxides. In this project perovskite-type Sr1-xBaxFe4+O3 and BaFe4+1-xMxO3 (M=Sn4+, Co4+…) have been successfully synthesized, and their magnetic properties have been investigated.
