Abstract

The original research results for thin disordered HTSC films based on YBCO are presented in this article. Several experiments have been carried out to confirm a theoretical prediction that the s-phase of superconducting pairing in disordered d-type superconductors can occur with a gradual decrease in the mean free path. The YBa₂Cu₃O_{7 – x} films are used as samples which possess a d-type of superconducting state that was experimentally confirmed. A gradual decrease in the mean free path was achieved by both thermal annealing and ion irradiation. The experiments included measurements of temperature dependence of the London penetration depth λ and resistive studies.

基于YBCO的HTSC薄膜超导配对中s成分的实验观察。

摘要

本文介绍了基于YBCO的无序薄HTSC薄膜的原始研究结果。已经进行了一些实验以证实理论上的预测，即无序d型超导体中超导对的s相会随着平均自由程的逐渐减小而发生。YBa ₂ Cu ₃ O _{7- x}薄膜用作具有d型超导态的样品，该超导态已通过实验证实。通过热退火和离子辐照均实现了平均自由程的逐渐减小。实验包括测量伦敦穿透深度λ的温度依赖性和电阻研究。
