Combined microstructural and magneto optical study of current flow in polycrystalline forms of Nd and Sm Fe-oxypnictides
F. Kametani, A. A. Polyanskii, A. Yamamoto +9
In order to understand why the inter- and intra-granular current densities of polycrystalline superconducting oxypnictides differ by three orders of magnitude, we have conducted co…

Evidence for two distinct scales of current flow in polycrystalline Sm and Nd iron oxypnictides
A. Yamamoto, A. A. Polyanskii, J. Jiang +13
Early studies have found quasi-reversible magnetization curves in polycrystalline bulk rare-earth iron oxypnictides that suggest either wide-spread obstacles to intergranular curre…
