摘要
研究了有机磁性聚合物ｐｏｌｙＢＩＰＯ链的封闭和非封闭结构对体系自旋密度波（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。
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.
