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