โฆ Synopsis
An experimental study of the existence conditions of a normal zone in a superconductor, containing high thermal and electrical contact resistance between the superconductor and the stabilizing normal metal, was carried out. The measurements conducted with a model short sample yielded the dependence of the length of a finite-sized normal region (resistive domain) on current and the current-voltage characteristic of such a sample. The electric field distribution in the resulting resistive structures was obtained.

The primary objective of this study is to examine the influence of operating temperature, ranging from 20 K to 80 K, and contact thermal resistance on the normal zone propagation in a silver-sheathed, YBCO superconductor tape. The distributions of temperature and heat generation are obtained numeric
