The magnetic and magnetotransport properties of Fe_3O_4/CoFe_2O_4/Fe_3O_4 trilayers were investigated. The magnetization measurements indicate significant Co diffusion into the bottom magnetite layer. At lower temperatures the magnetoresistance measurements show two clearly separated maxima due to contributions from magnetically hard and soft layers. A tunneling effect was not observed. Comparison of full and minor resistance hysteresis loops did not reveal any significant exchange coupling between the layers, presumably due to diffuse interfaces.
