Abstract

The irreversibility line in high-temperature oxide superconductors is theoretically investigated from a viewpoint of dependence on the flux-pinning strength and a general relation between the effective pinning potential and the critical current density is derived. It is shown that the irreversibility magnetic field at 77 K in strongly pinned oxide superconductors is sufficiently high for application.
