Abstract

The resistance and recovery properties of the YBCO thin-film wire according to the existence and thickness of an insulting layer, and the kinds of stabilization layers, were analyzed at 90 K, 180 K and 250 K. In this study, YBCO thin-film wires with different stabilizing layers and with insulating layers were examined in terms of their various characteristics, such as quenching occurrence, spread, and distribution, based on their resistance increase trends and their recovery from quenching, and the results were qualitatively explained. The results of this study on the characteristics of YBCO thin-film wires' superconducting and normal-conducting phase changes are expected to be useful in designing superconducting power machines and in improving their performance.
