Nanowires (NWs) from Fe-Co alloys with component ratios Fe : Co = 15 : 85, 52 : 48, and 65 : 35 are obtained by template synthesis in pores of track membranes 70 nm in diameter. The electrochemical deposition of NWs has been investigated, and the phase composition and specific features of the NW structure with a change in the Fe : Co ratio have been analyzed using transmission electron microscopy (TEM), scanning electron microscopy (SEM), electron diffraction, and energy-dispersive X-ray analysis (EDXA). It is established that crystallization of NWs is usually accompanied by the formation of a Fe-Co solid solution and (at Fe : Co = 65 : 35) an alloy with the preferred orientation of {100} planes along the NW axis. It is shown that lamellar crystals (mainly, iron oxides with the Fe3O4 stoichiometry) grow on the NW surface. These crystals increase in number and size (from several nanometers to 40 nm) with an increase in the iron content.
