Abstract

Hall probe array Magneto-optical imaging Melt-textured superconductor YBa 2Cu 3O 7
We use spatially resolved Hall probe magnetometry and magneto-optical imaging to study current-carrying properties of melt-textured high-temperature superconducting welds at high magnetic fields. The study of the vortex dynamics near the junction using high-resolution Hall probe magnetometry revealed enhanced relaxation of the magnetization at the junction at high temperatures. We attribute this behavior to an increased local concentration of defects near the weld which, depending on the temperature range, either facilitate enhanced relaxation or strengthen the local pinning properties.
