摘要
研究结果表明:对于一维更键（alternatingbond）铁磁链海森堡摸型，在一级近似下：（1）存在磁间隙孤子（振动频率位于磁频谱间隙内）和响应纽结（振动频率位于磁频谱内）．（2）内禀局域模（振动频率位于所有磁频谱带上方）是不可能存在的．
About the one dimension Heisenberg Ferromagnetics chain with bond alternation,our researched results show,in one approximation that (1) magnon gap solitons (with the vibrating frequency lying in the gap of magnon frequency band)and resonant kinks (with the vibrating frequency lying in the magnon frequency band) are found, (2)an instrinsic localized mode (with the vibrating frequency being above the magnon frequency band)is impossible.
