Magnetism And Phase Separation In Polymeric Hubbard Chains
We study a class of one-dimensional chains whose topology leads to flatbands in the electronic spectrum. Using the Hubbard model, we find that these materials should exhibit ferrimagnetic ordering for a half-filled band, in agreement with a theorem by Lieb. Away from half filling the system displays a very rich magnetic phase diagram. Possible experimental realizations are suggested.74101851185

A simple model for magnetism in itinerant electron systems
A new lattice model of interacting electrons is presented. It can be viewed
as a classical Hubbard model in which the energy associated to electron
itinerance is proportional to the total number of possible electron jumps.
Symmetry properties of the Hubbard model are preserved. In the half-filled band
with strong interaction the model becomes the Ising model. The main features of
the magnetic behavior of the model in the one-dimensional and mean-field cases
are studied.Comment: 9 pages, 3 figures, to be published in Physica
