Low-dimension ferromagnetic maghemite γ-Fe₂O₃ was synthesized through a precursor route, using basic iron formate Fe(OH)(HCOO)₂ as a precursor. Conditions of formation of γ-Fe₂O₃ and the temperature range of its existence on heating in air were determined. The saturation magnetization of γ-Fe₂O₃ produced through heating the precursor at 350°C 57.5 (T = 4.2 K) and 43.8 emu/g (T = 300 K).
