Orbital occupation and magnetic moments of tetrahedrally coordinated iron in CaBaFe4O7
Orbital occupation magnetic moments tetrahedrally coordinated iron
2010/11/25
CaBaFe4O7 is a mixed-valent transition metal oxide having both Fe2+ and Fe3+ ions in tetrahedral coordination. Here we characterize its magnetic properties by magnetization measurements and investigat...
A new dense silica polymorph: A possible link between tetrahedrally and octahedrally coordinated silica
