We study the charge ordering behavior in a three-dimensional extended Hubbard model using the Coherent potential approximation (CPA). It is shown that the charge ordering transition occurs due to the competition between kinetic and Coulomb energy. At various band fillings a simple reentrant behavior of the charge ordering transition is found.

We study the charge ordering behavior under magnetic field H in the extended Hubbard model within the coherent potential approximation. At quarter filling, for small H we find that the relative variation of critical temperature is quadratic with the coefficient α smaller than the one for conventional spin-Peierls systems. For intermediate fields, a melting of the charge ordering on decreasing temperature under fixed H at various band filling is found.
