摘要
Samples of multifilamentary Bi-2223 /Ag/Alloy twisted filament tapes and Z stack round wires, consisting of untwisted and twisted stacks (or z-arrays) of flat filaments have been prepared. It was found that twist pitches of less than 10 mm may be incorporated into multifilament tapes while maintaining the Jc at 20 kA/cm(2). The self field AC loss has been investigated at low frequencies up to 100 Hz. The round wire was found to exhibit isotropic electromagnetic properties.
