摘要
摘要:研究了铌酸钡(Ba2HoNbO6, BHNO)作为(Bi,Pb)2Sr2Ca2Cu3Ox (Bi(2223))超导体薄膜的新型衬底材料。Ba2HoNbO6具有立方钙钛矿结构，晶格常数a = 8·26 Å。这种材料的介电常数和损耗系数在一个范围内，适合作为微波应用的衬底。即使在极端的加工条件下，Bi(2223)超导体也不会与BHNO发生可检测到的化学反应。在Ba2HoNbO6衬底上浸镀Bi(2223)厚膜，在77 K和零磁场条件下，tc(0)为109 K，电流密度约为4 × 103 A cm - 2。
Superconducting Bi(2223) thick film on Ba2HoNbO6: a new perovskite ceramic substrate
Abstract Barium holmium niobate Ba2HoNbO6 (BHNO) has been developed as a new substrate for (Bi,Pb)2Sr2Ca2Cu3Ox (Bi(2223)) superconductor film. Ba2HoNbO6 has a cubic perovskite structure with lattice constant a = 8·26 Å. The dielectric constant and loss factor of this material are in a range suitable for its use as a substrate for microwave applications. The Bi(2223) superconductor shows no detectable chemical reaction with BHNO, even under extreme processing conditions. Dip coated Bi(2223) thick film on Ba2HoNbO6 substrate had T c(0) of 109 K and current density of around 4 × 103 A cm - 2 at 77 K and in zero magnetic field.
