| 摘 要： | 本文在强耦合极限下,讨论了一维扩展Hubbard模型的磁化率性质,并得到铁磁性、反铁磁性和顺磁性在此模型中都可能出现的结论。特别是在磁化率的表达式中出现了相当于有两种点阵存在时的交换积分J_1和J_2,而此模型只考虑了一种点阵。

| Abstract: | Magnetic susceptibility properties of the one-dimensional extended Hubbardmodel are discussed for strong-coupling. Ferromagnetism, antiferromagnetism andparamagnetism appeared in this model, especially, corresponds to exchange parame-ters J_1 and J_2 of two sublattices type appearing in the expression of magnetic sus- ceptibility. But a lattice type is only considered in this model. |
