Ferromagnetism in the Highly-Correlated Hubbard Model

Abstract:

Article Preview

The Hubbard model with strong correlations is treated in the many-electron representation of the Hubbard's operators. The regions of stability of saturated and non-saturated ferromagnetism in the n–U plane for the square and simple cubic lattices are calculated. The role of the singularities of bare density of states for the magnetic phase diagram is discussed. A comparison with the results of previous works is performed.
