磁单极、磁性和来自自旋冰的杂散场
Monopoles, magnetricity and the stray field from spin ice
摘要：
本文分析了自旋冰中μ介子在低温状态下的行为。它详细地示出了如何观察到的行为在一些以前的μ子实验自旋冰在弱横向磁场可能会导致磁化自旋冰的宏观杂散场。提出了一个模型，它允许这些宏观场效应进行模拟，结果与实验一致。在低温下持续的自旋动力学起源于样品，并且可能是μ子诱导的注入效应，其在具有长弛豫时间的非平衡系统中起作用。
英文摘要：
An analysis is presented of the behaviour of muons in the low-temperature state in spin ice. It is shown in detail how the behavior observed in some previous muon experiments on spin ice in a weak transverse field may result from the macroscopic stray field of magnetized spin ice. A model is presented which allows these macroscopic field effects to be simulated and the results agree with experiment. The persistent spin dynamics at low temperature originate from the sample and could be a muon-induced implantation effect that is operative in out-of-equilibrium systems with long relaxation times.
