Abstract
We have built a measuring system for investigating electrical conductance in nanowires. Our measurements concern nanowires formed in both magnetic and nonmagnetic metals. The statistical results (histograms) of the quantization are compared for nonmagnetic and magnetic nanowires. The results of conductance quantization in cobalt nanowires have not been presented before. We have observed conductance quantization of macroscopic metallic contacts in a circuit with a mechanical contact and with a LC circuit. The investigation has been performed outdoors at room temperature.
