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…
Evidence for electromagnetic granularity in the polycrystalline iron-based superconductor LaO0.89F0.11FeAs
A. Yamamoto, J. Jiang, C. Tarantini +13
The new rare-earth arsenate superconductors are layered, low carrier density compounds with many similarities to the high-Tc cuprates. An important question is whether they also ex…
Topological Hysteresis in the Intermediate State of Type-I Superconductors
Ruslan Prozorov, Russell W. Giannetta, Anatolii A. Polyanskii +1
Magneto-optical imaging of thick stress-free lead samples reveals two distinct topologies of the intermediate state. Flux tubes are formed upon magnetic field penetration (closed t…
