Abstract
The concentrational mechanism of ferromagnetic ordering has been consi dered from tile point of view of the Hubbard model with infinite inter action. It has been shown that the creation of ferromagnetic phase goe s through a phase separation and both saturation magnetization and Cur ie temperature are proportional to a density of doped electrons. Some experimental examples are discussed.
