研究了铁磁纳米管的磁开关特性及其几何特性。采用两种独立的方法：数值模拟和解析计算。研究发现，对于长管，磁化的反转是通过两种机制实现的：横向畴壁的传播或涡旋畴壁的传播，这取决于管的内外半径。(c) 2007年美国物理学会。
The magnetic switching of ferromagnetic nanotubes is investigated as a function of their geometry. Two independent methods are used: Numerical simulations and analytical calculations. It is found that for long tubes the reversal of magnetization is achieved by two mechanisms: The propagation of a transverse domain wall or propagation of a vortex domain wall depending on the internal and external radii of the tube.
