Flux pinning in BPSCCO (2223)-system

The flux pinning and magnetic shielding in highly oriented polycrystalline BiSrCaCuO superconductors are investigated in terms of the Bean-London model. The pinning potential in BPSCCO system of the [2223] single phase is weaker than that including the [2212] grains which act as strong pinning c...

Description
Summary:The flux pinning and magnetic shielding in highly oriented polycrystalline BiSrCaCuO superconductors are investigated in terms of the Bean-London model. The pinning potential in BPSCCO system of the [2223] single phase is weaker than that including the [2212] grains which act as strong pinning centers.
