摘要	The phase equilibrium in manganites under a magnetic field is studied using a two-orbital model, based on the equivalent chemical potential principle for competitive phases. We focus on the magnetic field induced melting process of the charge exchange (CE) phase in half-doped manganites. It is predicted that the homogeneous CE phase will begin to decompose into a coexisting ferromagnetic phase and CE phase once the magnetic field exceeds the threshold field. More quantitatively, the volume fractions of the two competitive phases in the phase separation regime are evaluated.
