Irreversibility Field and Pinning Potential in Bi-2212 Superconducting Single Crystal

  • Conference paper
Advances in Superconductivity XI

Abstract

The irreversibility field and the apparent pinning potential associated with the magnetic relaxation rate are observed for a Bi-2212 single crystal in the three-dimensional state of flux lines. It is tried to explain these irreversible properties by the flux creep theory using the same pinning potential. Fairly good agreements are obtained between theory and experiment. It is concluded that the flux creep theory correctly describes the irreversible properties of high-temperature superconductors.
