Abstract
We investigated cross-type specimens of two Sn whiskers with a metallic connection at their crossover. Applying a control current to one of the whiskers yields a tunable weak link (TWL) in the other whisker at the crossing point. The properties of the voltage-current characteristic generated by a phase-slip center developing at the TWL depend on the weakness of superconductivity in this region. The measurements show that the different behavior of phase-slip centers in Sn microbridges and Sn whiskers observed in former experiments may be a consequence of the different grade of homogeneity of these specimens. Finally, the weakening mechanism responsible for the weakening of superconductivity in the TWL is discussed.
