Özet
The formation of Ni nanocontacts using nanofabrication and thin film deposition techniques was discussed. The Ni nanocontacts had a three-dimensional point contact geometry with a minimum contact diameter in the range of 1-10 nm. The electron transport through these nanocontacts was shown to be ballistic or at least quasiballistic. It was found that depending upon the substrate preparation, the nanocontacts exhibited a strong magnetoresistance behavior in the presence of an in-plane magnetic field.
