Description |
“Magneto-optical imaging provides a powerful tool to the study of vortex instabilities in superconductors. This talk will describe magneto-optical studies of various classes of vortex instabilities, focusing on generation and annealing of transient vortex states and spontaneous generation of vortex oscillation in Bi-Sr-Ca-Cu-O crystals. Both these phenomena are observed in the vicinity of the vortex order-disorder phase transition. The physical origin of these phenomena, and their relationship to the vortex phase transition, will be discussed.” |
