Abstract
Two voltage jumps were found in the current–voltage characteristic of a thin superconducting film of Bi2Sr2CaCu2Ox at temperature 58 K. The fluorescent thermal imaging technique revealed a localized heat dissipation (hotspot) nucleated at the current causing the second jump, and the hotspots’ temperature is close to the critical temperature of the superconducting film.
Research highlights► We use the fluorescent thermal imaging (FTI) technique studying a thin BSCCO (2212) superconducting film at 58 K. ►In the current–voltage curve, two voltage discontinuities were found. ► By using FTI, we revealed that the only one discontinuity is associated with heat dissipation.
