Strong suppression of the resistivity near the transition to superconductivity in narrow micro-bridges in external magnetic fields

Xiaofu Zhang, Adriana E. Lita, Konstantin Smirnov +5

We have investigated a series of superconducting bridges based on homogeneous amorphous WSi and MoSi films, with bridge widths w ranging from 2 um to 1000 um and film thicknesses d…
