How vortices are pinned by low-angle grain boundaries in a (Ba,K)Fe2As2 superconductor

Caption

Schematic illustration of how vortices are pinned by low-angle grain boundaries in a (Ba,K)Fe2As2 superconductor. The pinning force density Fp of (Ba,K)Fe2As2 thin film fabricated in this study is almost 10 times as high as a pristine single crystal.
