Abstract
AbstractIn this chapter we present the fabrication and characterization of superconducting tungsten nanodeposits grown by focused ion beam induced deposition. First, we study the influence of some deposition parameters, such as ion beam voltage, ion beam current, and incidence angle of the focused ion beam, on the nanodeposits’ composition. Second, we present the superconducting properties of tungsten deposits of varying width, from microwires to ultranarrow nanowires of 50 nm width, by means of magnetotransport measurements. Finally, we study the nonlocal voltage generated in tungsten nanowires by nonlocal magnetotransport measurements. The results allow us to link this kind of superconducting nanostructures to potential applications in nanotechnology.KeywordsApplied Magnetic FieldCritical Current DensityBias CurrentVortex LatticeTungsten DepositThese keywords were added by machine and not by the authors.
