Fig. 2 — a The effect of the O₂ concentration in the DI water on the charge transfer between the (a) Fe₃O₄ and (b) CoFe₂O₄ samples and the DI water. c The effect of the magnetic field on the CE between the Fe₃O₄ sample and different organic solutions. d The relationship between the O₂ concentrations in the organic solutions and the magnetic field-induced charge transfer between the Fe₃O₄ sample and the organic solutions. e The magnetic field-induced charge transfer between the Fe₃O₄ and CoFe₂O₄ samples and the DI water at different temperatures. f The effect of temperature on the magnetic moments of the Fe₃O₄ and CoFe₂O₄ samples in a 0.5 T magnetic field.
