摘要/Abstract

摘要：

利用低氟MOD工艺制备了Ba₂YTaO₆(BYTO)单一纳米颗粒掺杂及BYTO和LaAlO₃(LAO)双纳米颗粒共掺杂的YBCO复合薄膜。研究表明BYTO在YBCO薄膜中的最优掺杂量为6mol%, 此时薄膜的自场J_c为1.25 MA/cm ², 在1.2 T下获得的最大钉扎力为3.02 GN/m ³。共掺杂试验中引入与YBCO具有正错配度的BYTO粒子和负错配度的LAO粒子, 两者相互作用使有效掺杂总量提高至10mol%。调整两种纳米粒子的配比发现6mol% BYTO+4mol% LAO掺杂的YBCO复合薄膜样品在外加磁场为2 T时, J_c值高达0.27 MA/cm ², 获得最大钉扎力时的磁场由纯YBCO薄膜的0.42 T提高至共掺杂的1.6 T, 此时最大钉扎力为5.6 GN/m ³。正负错配纳米颗粒共掺杂有效地提高了YBCO复合薄膜在外加磁场下的超导性能。

Abstract:

The YBCO composite films doped with Ba₂YTaO₆ (BYTO) single nanoparticles and BYTO/LaAlO₃(LAO) double nanoparticles were prepared by low-fluorine MOD process. The result showed that the optimum doping amount of BYTO in YBCO film was 6mol%, when the self-field J_c of this film was 1.25 MA/cm ², and the maximum pinning force was 3.02 GN/m ³ at 1.2 T. In the co-doping experiment, BYTO particles with positive lattice mismatch with YBCO and LAO particles with negative lattice mismatch with YBCO were introduced, and the interaction between two particles increased effective doping amount up to 10mol%. With adjustment of the ratio of the two kinds of nanoparticles, it was found that the 6mol% BYTO+4mol% LAO-doped YBCO composite films had a J_c value as high as 0.27 MA/cm ² when the magnetic field was 2 T. This magnetic field in which the maximum pinning force was obtained, increased from 0.42 T for pure YBCO to 1.6 T for codoping, in which the maximum pinning force was 5.6 GN/m ³. The co-doping with positive and negative lattice mismatch nanoparticle effectively improves the superconductivity of YBCO composite film under applied magnetic field.
