Ap. Zhuravel et al., SPATIALLY-RESOLVED STUDY OF TRANSITION TO THE PHASE-SLIP LINES RESISTIVE STATE IN WIDE SUPERCONDUCTING STRIPS, Czechoslovak journal of Physics, 46, 1996, pp. 643-644
The voltage images of nonequilibrium resistive state associated with a
phase-slip lines (PSLs) formation in a current-carrying superconducti
ng Sn strip were obtained using low-temperature scanning laser microsc
opy (LTSLM). The transition to the PSLs started from dynamic-mixed sta
te by single PSL nucleation. The number of PSLs increases rapidly whil
e increasing the current density, the spatial rearrangement of the who
le resistive structure being observed.
