摘要: 利用微帶諧振技術研究了YBa₂Cu₃O₇/LaAlO₃(YBCO/LAO)和YBa₂Cu₃O₇/MgO(YBCO/MgO)超導薄膜的微波響應.通過測量微帶諧振器的共振頻率、有載品質因數、插入損耗與溫度之間的依賴關系,分析了超導薄膜的微波特性,獲得了超導薄膜在絕對零度時的穿透深度λ₀.對于YBCO/LAO,λ₀=265nm;對于YBCO/MgO,λ₀=280nm.本文還利用微帶諧振器研究了YBCO/LAO和YBCO/MgO超導薄膜的微波表面電阻.

Abstract: The microwave response of YBa₂Cu₃O₇/LaAlO₃ (YBCO/LAO) and YBa₂Cu₃O₇/MgO (YBCO/MgO) superconducting thin films was studied by microstrip resonator technique. Microwave characteristics of the superconducting films were analyzed by the temperature dependence of resonant frequency, load quality factor and insert loss. The penetration depth at 0 K can be attained as:λ₀=265 nm for YBCO/LAO and λ₀=280 nm for YBCO/MgO. The microwave surface resistance Rs of YBCO/LAO and YBCO/MgO was also investigated by microstrip resonator.
