Popis: The conditions for the emergence of inhomogeneous states are investigated from analysis of the equation of state. It is assumed that Hubbard energy U > t, i.e., corresponds to the conditions of strong electron–electron correlations. The magnetic phase diagram is obtained in a wide range of electron concentrations corresponding to the lower Hubbard band.
