摘要
The field-induced dynamics of artificial spin ice are determined in part by interactions between magnetic islands and the switching characteristics of each island. Disorder in either of these affects the response to applied fields. Numerical simulations are used to show that disorder effects are determined primarily by the strength of disorder relative to inter-island interactions, rather than by the type of disorder. Weak and strong disorder regimes exist and can be defined in a quantitative way. (C) 2012 American Institute of Physics. [doi:10.1063/1.3671434]
