摘要：

We have fabricated Y-Ba-Cu oxide (YBCO) thin-film microbridges having a restricted region with an artificial weak-link structure where Au has been diffused into or reacted with the YBCO at some grain boundaries. In these microbridges, we have confirmed a microwave response exhibiting current steps and linear or exponential-like temperature dependence of the critical current near Tc. In contrast to this, microbridges without an artificial weak-link structure are virtually responsive to the microwave, and their temperature dependence of the critical current is like that of a granular microbridge. © 1990 IOP Publishing Ltd.
