heal.abstract	We report a complete multicomponent mean-field-theory for the coexistence andcompetition of charge ordering (CO), antiferromagnetic (AFM) and ferromagnetic(FM) spin ordering in the presence of a uniform magnetic field. Doping the AFMor CO state always generates a ferromagnetic component. Itinerant FM, AFM andCO, necessarily coexist and compete in a particle-hole asymmetric system.Melting of large AFM-CO orders	en
