Nanostructured composites based on TiO 2  doped with Mn were obtained by sol-gel template method. The morphology and structure of the composites were studied by x-ray diffraction, scanning and transmission microscopy, X-ray photoelectron spectroscopy. Electrical conductivity and magnetic properties are investigated. It is shown that the doping of TiO2 samples with manganese improves conductivity by two orders of magnitude in comparison with a non-doped sample. Changing the annealing conditions of the nanostructured composite increases the conductive properties four times. It is established that the studied samples have ferromagnetic ordering at room temperature, and the saturation magnetization value and the slope angle of the curve M(H) depend on the annealing conditions, the presence of a magnetic transition in the region of 45 K corresponding to the transition Mn 3 O 4  to the ferrimagnetic state is determined.
