Abstract
- The temperature dependencies of the electrical resistance are reported for bundles of permalloy, indium, tin, and lead nanowires having a similar diameter of about 8 nm which were grown by catalytic coagulation of laser ablation products in quantized vortices of superfluid helium. In all metals, the constant residual resistance found at low temperatures changes to a superlinear growth at higher temperatures. For all superconducting nanowires, the transition to superconductivity is broadened with a width of δT = 0.6 K. The size shift of the transition center ΔT is largest for lead, ΔT = −2 K, whereas for indium and tin ΔT is 0.2 K and
