自旋S=1的各向异性磁体的半经典描述
Semiclassical description of anisotropic magnets for spin S=1
摘要:
本文在实参数化下利用广义相干态研究了一维非Heisenberg铁磁模型的非线性方程组。当从基态有一个小的线性激发时,得到了偶极和四极分支的耗散自旋波方程。
英文摘要:
In this paper, nonlinear equations describing one-dimensional non-Heisenberg ferromagnetic model are studied by use of generalized coherent states in a real parameterization. Also dissipative spin wave equation for dipole and quadruple branches is obtained if there is a small linear excitation from the ground state.
