Ferromagnetism in the Highly-Correlated Hubbard Model
Strongly Correlated Electrons
2011-01-25 v1
Abstract
The Hubbard model with strong correlations is treated in the many-electron representation of 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 bare density of states singularities for the magnetic phase diagram is discussed. A comparison with the results of previous works is performed.
