Rectangular normal domains in current-carrying superconductors

摘要

We find a type of normal domain in composite superconductors-a traveling rectangular domain. Using the effective circuit model we study in detail the dynamics of this domain. We derive an analytical solution for the propagation velocity and the length of a traveling rectangular domain. Current-voltage characteristics are calculated for a superconductor with a rectangular domain. (C) 1998 American Institute of Physics, S0021-8979(98)03811-0 References: 12
