| Research Abstract |
Ag-sheathed high-temperature superconducting tapes used as strands of superconducting power cables are exposed to magnetic fields and transport currents under AC operation, so that both of magnetization losses and transport losses generate therein simultaneously. The former contribution to total AC losses becomes predominate with increasing magnetic field, and it should be reduced by suppression of electromagnetic coupling among superconducting filaments in the tapes. We report here the developments of Ag-sheathed superconducting tapes with low magnetization lossesby introduction of inter-filamentary oxide barriers.
