A mixed magnetite/maghemite solid solution and a bentonite/iron oxide composite material were synthesized using the chemical coprecipitation method. It was found that composite bentonite/iron oxides have significantly lower residual magnetization and higher coercive force compared to Fe₃O₄/γ-Fe₂O₃ powder. Based on experimental diffraction and Mössbauer spectroscopy data, conclusions were drawn about the influence of bentonite on the structural features of magnetite/maghemite in the composite.
