摘要	We carry out Density Matrix Renormalization Group (DMRG) calculations on the interchain coupling model for the quasi-one-dimensional organic ferromagnets under open boundary condition. Considering the topology of the system, the two-step DMRG technique is adopted. It is found that in the high spin ground state of the system the interchain coupling is in favor of the stability of ferromagnetic state, and the on-site electron-electron repulsive interaction has the same effect. However the inter-site electron-electron interaction causes a charge density distribution along the main chain and weakens the stability of the ferromagnetic ground state. The lattice distortion along the main chain is also discussed.
