| 摘 要： | Thermomagnetic instability is a crucial issue for the application of superconductors.Effects of edge cracks on the thermomagnetic instability of superconducting thin films are systematically investigated in this work.Dendritic flux avalanches in thin films are well reproduced through electrodynamics simulations,and relevant physical mechanisms are revealed from dissipative vortex dynamics simulations.It is found that edge cracks sharply decrease the threshold field for the thermomagnetic instabi...
