摘要：

Ferromagnetic nanowires of Fe have been fabricated by molecular-beam epitaxy on a vicinal W(110) single-crystal surface with steps along the [001] direction. The magnetic properties were investigated by Kerr magnetometry. The magnetic easy axis is in the substrate plane and perpendicular to the steps. The remanent magnetization disappears near T-c in a temperature range much narrower than predicted by standard theory of finite-sized systems. Above T-c, the magnetization can be saturated in saturation fields H-s which are small compared to two-dimensional systems. (C) 1998 Elsevier Science B.V. All rights reserved.
