在无磁场的情况下，在镍丝和镍膜的断裂结合处形成的铁磁性镍纳米线的电导以2e2/h为单位被清楚地量化。然而，当存在高于镍丝的饱和场的磁场时，电导量化单元切换到e2/h。这表明铁磁纳米线的电导量子化与纳米线的磁性结构密切相关。
Conductance of a ferromagnetic Ni nanowire formed at a break junction between Ni wire and Ni film is clearly quantized in units of 2e2/h in the absence of magnetic fields. The conductance quantization unit, however, switches to e2/h in the presence of magnetic fields higher than the saturation field of the Ni wire. This indicates the conductance quantization in a ferromagnetic nanowire is closely related to magnetic structure of the nanowire.
