Normalphase propagation with increasing temperature level in hightemperature superconductors
Abstract
Three regimes are identified in the normalphase propagation in a hightemperature superconductor. When the current (i) is less than the critical current (iasterisk), an ordinary bistable wave of finite amplitude propagates. When i is greater than iasterisk, the system is 'monostable' with the propagation of an autowave with an exponentially increasing crest and a constant front velocity. However, if in the ranges i less than i sub 1, i greater than i sub 2 this velocity is determined by the entire form of the source, in the range i sub 1 less than i less than i sub 2, it is determined only by the increase in the resistance of the normal substrate.
