【摘要】 在YSZ双晶基片上，制备了双晶高TcGdBa₂Cu₃O（7-δ）超导薄膜，晶界夹角为24°。采用光刻技术在晶界上刻出了不同尺寸的晶界结，观测了结的直流I－V特性和在10GHz微波辐照下结临界电流的压缩和Shapiro台阶，表明双晶结具有约瑟夫逊弱连接行为。在实验基础上，对结的特性进行了理论分析和数值模拟。更多还原

【Abstract】 The high Tc GdBa2Cu3O7-δ thin films have been fabricated on YSZ bicrystal substrate.The GBJ. were fabricated by photeetching technic. The DC I - V characteristic and I - V characteristic under microwave irradiation of GBJ were measurement. On the base of cxperimental, the theoretical analysis and phenomenon model of GBJ were performed. The Josephson weak link characteristics were shown by experimental results of our GBJ.更多还原
