摘要:
The mechanism of hypervortex pinning in a granular superconductor at intergranular contacts and intragranular defects is proposed for describing the field dependence of the critical current density and pinning potential. The results are in good agreement with those obtained experimentally. The proposed model describes the peak effect and the percolation mechanism of conductivity in ceramic superconductors. ©1998 American Institute of Physics.
