In order to enhance and/or control critical current density ( J c ) in superconducting YBa 2 Cu 3 O ##IMG## [http://ej.iop.org/images/0953-2048/33/10/105006/sustabacb0ieqn2.gif] {$_{7-\delta}$} (YBCO) thin films, different arrays of 3 µ m large ferromagnetic (iron) dots with differing configurations and shapes have been deposited on top of high-quality YBCO thin films post-buffered with a layer of CeO 2 . Some tremendous J c enhancement of up to nearly 100% have been obtained at high temperatures and low fields. However, the J c performance is strongly dependent on the array configurations, shape and amount of ferromagnetic iron involved. We show that it is possible to enhance J c at high or low magnetic field ranges. The results are clearly different to similar non magnetic array structures used to previously manipulate ...

为了增强和/或控制超导YBa 2 Cu 3 O中的临界电流密度（J c）## IMG ## [http://ej.iop.org/images/0953-2048/33/10/105006/ sustabacb0ieqn2.gif] {$ _ {7- \ delta} $}（YBCO）薄膜，在高质量YBCO薄膜上已沉积了3微米的具有不同配置和形状的大铁磁（铁）点阵列后用一层CeO 2缓冲。在高温和低场下，J c的提高幅度高达近100％。但是，J c性能在很大程度上取决于阵列结构，所涉及的铁磁铁的形状和数量。我们表明可以在高或低磁场范围内增强J c。结果明显不同于以前用于操纵...的非磁性阵列结构。
