Abstract
Considering interchain interaction and the intrachain next-nearest neighboring hopping interaction, within the self-consistent-field Hartree-Fock approximation, we deal with two neighboring organic ferromagnetic chains. We also take into account the itineracy of π-electrons, the Hubbard repulsion and antiferromagnetic correlation between π-electrons and side radical electrons. It is shown that there appear two kinds of CDW successively when the next-nearest neighboring hopping interaction is greater than a critical value, which decreases with the interchain coupling. The first CDW is accompanied with bond-order-wave and the second one with no distortion of lattice. The SDW along the main chain is modulated by the CDW. It is also found that the interchain coupling and the next-nearest neighbor hopping integral instabilizes the ferromagnetic ground states.
