| 中文摘要 | Instanton configurations of 1+1 dimensions in a ferromagnetic biaxial-anisotropy-spin chain are obtained explicitly in the strong-anisotropy limit, and macroscopic quantum coherent tunneling of domain walls is illustrated in terms of the instantons. The tunneling amplitude for an instanton configuration is obtained and the result shows that it is possible to have a finite-energy splitting of the degenerate orientations of the magnetization for a finite-length spin chain at finite temperature. |
