| 中文摘要 | Quantum tunneling effect at excited states in antiferromagnetic particles is studied with the help of the periodic instanton method. The transition amplitude, energy shift and prefactor of WKB exponential are given for various low-lying excited states. The tunneling rate at definite temperature is obtained by statistical average and the theoretical dependence of the tunneling rate on temperature is in agreement with the experimental results. |
