It is usually considered that the story of magnetism begins with a mineral called magnetite (Fe 3 O 4 ), the first magnetic material known to man. However, the oxidation of magnetite, which occurs at very low temperatures ( > 50 °C), results in maghemite (γ-Fe 2 O 3 ). Both are very similar materials in structure (spineltype) and ...
