Essay

The many-band Hubbard model is generalized on disordered alloys case and the method of calculation of the energy spectrum, kinetic properties and magnetic phase diagram of the systems with strong electron correlations is developed. Magnetic phase diagram of transition metals with narrow d-bands is built. The exact limits of phase regions are determined. The influence of electron correlations on metal-insulator and order-disorder phase transition is studied. An electronic properties, atomic and magnetic ordering of intermetallic alloy Fe50Ti50 were calculated.
