Flux Dynamics in Inhomogeneous Bulk Superconductor During Pulsed Field Magnetization

The inhomogeneous distribution of critical current density in a bulk superconductor is one of the most important properties for understanding the pulsed field magnetization method (PFM). In this paper the flux dynamics in the bulk superconductor during pulsed field magnetization (PFM) were studied by a three-dimensional finite element method considering the inhomogeneous distribution of critical current density
