摘要:The basic properties of quasi-one-dimensional organic ferromagnet are investigated based on extended SSH (SSH=Su-Schrieffer-Heeger)+Heisenberg model, by taking into account the electron hopping between main chain and side radicals. First, it is found that the lattice dimerization decreases until disappear with the electron delocalization and the electron-electron (e-e) interaction affects the amplitude of dimerization. Then, the spin density wave (SDW) is also considered in different e-e interactions when the organic ferromagnet lies in ground state. The results show that the SDW on the main chain increase with the electron delocalization, the on-site e-e interaction is advantageous to the forming of SDW on the main chain while the effect of inter-site repulsion is contrary.
