AC losses in multifilamentary HTS-composite tapes based on BiPbSrCaCuO

Investigation of Bi-2223 high temperature superconducting tape as the material for gradient coil in MRI

“…Previously, measurement of the power loss in Bi-2223 HTS tapes has focused on low frequency applications below 600 Hz [13][14][15] instead of the typical 1-2 kHz at which gradient coils work.…”
