Abstract
Measurement is made of the transition to the resistive state of nearly one-dimensional superconducting microbridges of indium. The length of the microbridges ranged from 30 to 130 µm. The experiments concentrated in particular on the onset and temperature dependence of the hysteresis of the voltage-current characteristic, the temperature dependence of the excess current, and the equivalent normal length of the phase-slip centers generated during the resistive transition. The results are in good agreement with the dynamic model of a phase-slip center proposed by Kadin, Smith, and Skocpol.
