我们介绍了电沉积法制备的镍镍和钴镍磁性纳米触点的电导和磁阻测量。在室温下，Ni-Ni缩窄体在分解成e(2)/h单位时表现出广泛的电导率量化平台，这与铁磁弹道纳米触点的预期一致。此外，还测量了Co-Ni纳米触点的正磁电阻和负磁电阻。(C) 2003年美国物理研究所。
We present conductance and magnetoresistance measurements in magnetic Ni-Ni and Co-Ni nanocontacts prepared by electrodeposition within the pores of a track-etched polymer membrane. At room temperature, Ni-Ni constrictions show broad quantization plateaus of conductance during their dissolution into units of e(2)/h, as expected for ferromagnetic ballistic nanocontacts. Additionally, positive and negative magnetoresistance has been measured in Co-Ni nanocontacts. (C) 2003 American Institute of Physics.
