We report thin films of ferromagnetic Fe$\text{}_{3}$O$\text{}_{4}$ (magnetite) grown by a reactive magnetron sputtering at T=300÷450°C on lattice-matched MgO, and bilayer structures composed of Fe$\text{}_{3}$O$\text{}_{4}$ and underlying epitaxial films of highly conductive electron-doped In$\text{}_{2}$O$\text{}_{3}$〈Sn〉, LaNiO$\text{}_{3}$, and antiferromagnetic CoO. The prepared Fe3O4/MgO films and the bilayer structures demonstrated clearly defined resistance anomaly at Verwey transition point (T$\text{}_{V}$≈100-120 K). Formation of high resistance interlayer was indicated between the adjacent conducting Fe3O4 and LaNiO3 layers. However, relatively low interface resistivity of about 0.1 Ω cm$\text{}^{2}$ (at T=300 K) was estimated for the patterned Fe3O4/In2O3〈Sn〉 bilayer structures. Vertical electrical transport measurements revealed strong nonlinearity in the I-U dependences of the Fe3O4/In2O3 〈Sn〉 interface at T
