论文摘要
在这篇综述中，我们追踪处理非类别旋转构型的量子自旋理论的演变。非共线旋转配置是竞争互动造成的挫败感的后果。它们包括由于竞争最近的邻居（NN）而引起的简单手性磁铁，以及与几何挫败感的Next NN相互作用和系统，例如三角形抗Ferromagnet和Kagomélattice。我们在此处审查了此类系统的自旋波结果以及Dzyaloshinskii-Moriya相互作用的系统。重音是在这些非结合基态上提出的，这些基础状态必须在应用任何自旋波理论以确定基本激发的频谱之前必须计算出来。我们主要显示通过使用绿色功能方法获得的结果。这些结果包括逐层的自旋色散关系和磁化，作为2D，3D和薄膜中$ t $的函数。还包括一些新的未发表结果。显示和讨论了有关该方法的技术细节和讨论。
In this review, we trace the evolution of the quantum spin-wave theory treating non-collinear spin configurations. Non-collinear spin configurations are consequences of the frustration created by competing interactions. They include simple chiral magnets due to competing nearest-neighbor (NN) and next-NN interactions and systems with geometry frustration such as the triangular antiferromagnet and the Kagomé lattice. We review here spin-wave results of such systems and also systems with the Dzyaloshinskii-Moriya interaction. Accent is put on these non-collinear ground states which have to be calculated before applying any spin-wave theory to determine the spectrum of the elementary excitations from the ground states. We mostly show results obtained by the use of a Green's function method. These results include the spin-wave dispersion relation and the magnetizations, layer by layer, as functions of $T$ in 2D, 3D and thin films. Some new unpublished results are also included. Technical details and discussion on the method are shown and discussed.
