Nb^5＋掺杂对低氟MOD法制备的YBCO薄膜性能的影响
Source abstract
Abstract
本研究通过低氟MOD法成功地制备了Nb 5+ 掺杂的YBa 2 Cu 3 O 7- x (YBCO)薄膜, Nb 5+ 在薄膜中生成了大小在20~30 nm之间的纳米颗粒; 纳米颗粒的生成不会对 YBCO薄膜的织构和临界温度( T c )构成明显的影响。由于纳米颗粒的引入, 掺杂后薄膜的临界电流密度( J c )在整个磁场范围内都要高于纯的YBCO, 自场下的Jc更是达到了3.4 MA/cm 2 。掺杂薄膜的钉扎力( F p )也远远大于纯YBCO, 最大钉扎力达到了3.25 GN/m 3 , 有效地提高了YBCO在外加磁下的超导性能。
