摘要	We propose a theoretical model for anisotropic multiferroics, which are one-dimensional charge transfer magnets. By means of Green's function theory, ferroelectric and magnetic properties are studied. It is found that the anisotropy not only plays an important role on the ferroelectric phase transition but also enhances the ferroelectric polarization. Under different anisotropy, the phase diagram and temperature dependence of the magnetic susceptibility and dielectric constant are also presented. It reveals that the transition temperature increases as anisotropy ascends, which is attributed to the energy gap. These results put forward a way to enhance the ferroelectric phase transition temperature. (C) 2013 AIP Publishing LLC.
