Nanoscale pinning centers are introduced into YBa 2 Cu 3 O 7 (YBCO) films and tapes to improve vortex pinning and critical current density ( J c ) for coated conductor application. While pinning with a single type of pinning center has been mainly investigated, hybrid pinning with multiple types of pinning center is expected to be more promising for simultaneously achieving high J c values and suppressing J c anisotropy. In the present study, a three-phase-nanocomposite film consisting of an YBCO matrix, BaHfO 3 nanorods and Y-O nanoparticles was fabricated. A global pinning force maximum ( F p,max , where F p = J c B ) of 1.57 TN m −3 at 4.2 K, which is as high as the record level of F p,max , was achieved by the hybrid pinning of BaHfO 3 nanorods and Y-O nanoparticles. Furthermore, the hybrid pi...

通过YBa 2 Cu 3 O 7三相纳米复合薄膜的混合钉扎同时实现高J c和抑制J c的各向异性。

将纳米级钉扎中心引入YBa 2 Cu 3 O 7(YBCO)薄膜和胶带中,以改善涡旋钉扎和临界电流密度(J c),以用于涂覆导体。虽然已经主要研究了用单一类型的钉扎中心进行的钉扎,但是在同时获得高J c值和抑制J c各向异性的同时,使用多种类型的钉扎中心的混合钉扎被认为更有希望。在本研究中,制作了由YBCO基质,BaHfO 3纳米棒和YO纳米颗粒组成的三相纳米复合膜。通过4.2 K的混合钉扎力实现了在4.2 K时1.57 TN m -3的全局钉扎力最大值(F p,max,其中F p = J c B)。 BaHfO 3纳米棒和YO纳米颗粒。此外,混合动力汽车...
