摘要

Based on a theoretical model proposed for interchain coupled quasi-one-dimensional organic ferromagnets, the stability of the high-spin ground state of the system is studied. The non-nearest neighbor hopping interactions as well as the electron-phonon and electron-electron interaction are taken into account. It is shown that when the second-nearest neighbor hopping interaction increases, the energy gap decreases, which destablizes the ferromagnetic ground state while the third-nearest neighbor hopping interaction makes it stable.
