Abstract

Metallic substrates and sheaths in practical high-Tc superconductors will produce extra losses in ac operation. These losses are investigated in general, and applied to the case of a Ag or Ag-Mg sheath, and a Ni-alloy substrate, for the range of frequencies used in power systems (order of 100 Hz). For generality a ferromagnetic substrate is considered, but in a thin tape the ferromagnetism is found to have little effect on the principal loss, which is an eddy current loss for a magnetic field applied perpendicular to the face of the tape.
