▎ 摘　　要

Graphene nanoscrolls (GNSs) have attracted more and more attention both in theory and experiments for their unique and excellent fundamental properties and the wide range of potential applications. In this paper, the fabrication of GNSs with different ferromagnetic nanowire (FNW) templates has been studied by molecular dynamics (MD) method. We have presented convincing explanations on the GNS formation mechanism and a thorough analysis about the differences between varying FNWs. Moreover, a distinctive deformation behavior in the Ni nanowire oriented in [0 0 1] axis direction was observed and deeply investigated. And the influence of nanowire lengths on the fabrication of GNS is also studied. Our theoretical results will provide researchers a powerful guide and helpful assistance in designing better targeted programs in experiments. (C) 2015 Elsevier B.V. All rights reserved.
