Vortex Pinning of Ba 0.62 K 0.38 BiO 3 Investigated by Magneto-Optical Kerr-Effect and Magnetization Measurements

Vortex pinning plays a crucial role in determining properties of type-II superconductors. For example, it governs the irreversible magnetic response as well as dissipation caused by vortex motion. Here, we study vortex pinning in the three-dimensional oxide superconductor Ba 1− x...
