Overview

Maghemite (Fe2O3, γ-Fe2O3) is a member of the family of iron oxides. It has the same formula as hematite, but the same spinel ferrite structure as magnetite (Fe3O4) and is also ferrimagnetic. It is sometimes spelled as "maghaemite". Maghemite can be considered as an Fe(II)-deficient magnetite with formula (FeAIIIA8)A[FeAIIIA403◻A83]BOA32 where ◻ represents a vacancy, A indicates tetrahedral and B octahedral positioning.
