| 摘 要： | 研究了有机磁性聚合物ploy-BIPO链的封闭和非封闭结构对体系自旋密度（SDW)的影响.在开链情况下，自旋耦合与电子-电子相互作用对主链SDW的形成存在竞争，自旋耦合有利于SDW的形成；而电子-电子相互作用对SDW起到抑制作用.闭环下，没有得到这些结论.

| Abstract: | Spin density wave in organic ferromagnets with open ends was studied and the results were compared with that in a closed organic ferromagnet ring. It was found that an end-open chain structure is unfavorable for the formation of the ferromagnetic ground. The competition of electron-electron interactions and the π-electron-radical spin couplings and their different effect on the SDW in the main chain were discussed. |
