WebJul 4, 2010 · The spinel ferrite structure with the formula of MFe 2 O 4 (M = Co, Ni, Zn, or other metals) can be described as a cubic, closely packed arrangement of oxygen atoms, and M 2+ and Fe 3+ ions can occupy either tetrahedral (A) or octahedral (B) sites [ 1 ]. WebJan 1, 2024 · Such ferrites are in fact a prototype of naturally occurring ferrites, i.e., FeO·Fe 2 O 3. The spinel structure is derived from the mineral spinel (MgAl 2 O 4 or MgO·Al 2 O 3 ), which crystallizes in the cubic system [ 18 ]. This crystal structure was first determined by Bragg [ 19] and by Nishikawa [ 20 ].
