铁磁环境中的稀释反铁磁体

Diluted antiferromagnet in a ferromagnetic enviroment

M. O. Hase, J. F. F. Mendes

摘要:

在临界现象的框架下处理随机“攻击”下网络的鲁棒性问题。研究了铁磁系统的自发磁化对反铁磁相互作用随机夹杂的持续性。在检查了模型的淬火版本(相对于随机反铁磁相互作用)的静态特性后,还在退火近似下分析了磁化强度的持久性,并讨论了结果的差异。

英文摘要:

The question of robustness of a network under random ``attacks'' is treated in the framework of critical phenomena. The persistence of spontaneous magnetization of a ferromagnetic system to the random inclusion of antiferromagnetic interactions is investigated. After examing the static properties of the quenched version (in respect to the random antiferromagnetic interactions) of the model, the persistence of the magnetization is analysed also in the annealed approximation, and the difference in the results are discussed.
