YBCO 块材桥特殊实验现象原因初探

PRELIMINARY EXPLORATION OF THE REASON FOR REASON FOR PARTICULAR PHENOMENON ON YBCO BULK BRIDGE

本文通过对两个串联颗粒边界结 I～V 曲线的分析,对 YBCO 超导“大桥”在 Josephson 效应实验中,分别只出现标号为2n、2n+1、3n 微波感应台阶及大量丢失台阶的现象作了直观的定性解释。

In term of the diagrammatic analysis of I-V curve of two grain b-oundary junctions in series this paper gave the audio-visual qualitative explaination on the microwave-induced current steps of number 2n, 2n+1, 3n and the phenomenon of many missed steps appeared in the I-V curve of Josephson effect experiment for YBCO large bridge.
