Ag. Sivakov et al., LASER-SCANNING VISUALIZATION OF EVOLUTION OF VORTEX INSTABILITY IN CURRENT-CARRYING SUPERCONDUCTING STRIPS, Czechoslovak journal of Physics, 46, 1996, pp. 877-878
The low temperature scanning laser microscopy is used to study spatial
characteristics of current-induced resistive states in wide supercond
ucting Sn films. The irregularities of edge potential barrier and the
current distribution in a film cross section are visualized. The resul
ts are in good qualitative agreement with Aslamazov-Lempitsky theory.
