Lett. 103, 082601 (2013); http://dx.doi.org/10.1063/1.48190740003-6951http://hdl.handle.net/10919/47412In this study, we demonstrated superconductivity in a fiber with a lead core and fused silica cladding. The fibers were fabricated via a melt-draw technique and maintained overall diameters ranging from 200-900 mu m and core diameters of 100-800 mu m. Superconductivity of this fiber design was validated via the traditional four probe test method in a bath of liquid helium at temperatures on the order of 4 K. The superconducting fiber paves the way for applications in power transmission, magnetic sensing, and fundamental studies in the fields of electromagnetism.
