Abstract

The goal of this study is to investigate the mechanisms that are responsible for the dissipation in various polycrystalline high-temperature superconductors. The importance of grain connectivity for the conductors to sustain a large supercurrent is demonstrated. The question in how far poor grain connectivity reduces the critical current density and influences its behavior in magnetic field is addressed. The location of the dissipation mechanisms is revealed and the mechanisms are studied independently.
