摘要：
Samples of the Fe-Al-Co system are obtained electrochemically in a water solution. The kinetic dependences that describe the processes that occur in microparticles of aluminum in water solutions are established. The phase composition of the synthesized samples is determined via X-ray diffraction and Mossbauer spectroscopy. It is shown that the main contribution to the fine magnetic structure of Fe-Al-Co is made by the magnetically ordered structure with a hyperfine field around 348 kOe formed by a mechanical mixture of FeCo and Al.
