Flux transformers made of commercial high critical temperature superconducting wires

We have designed flux transformers made of commercial BiSCCO tapes closed by soldering with normal metal.

Zusammenfassung:	We have designed flux transformers made of commercial BiSCCO tapes closed by soldering with normal metal. The magnetic field transfer function of the flux transformer was calculated as a function of the resistance of the soldered contacts. The performances of different kinds of wires were investigated for signal delocalization and gradiometry. We also estimated the noise introduced by the resistance and showed that the flux transformer can be used efficiently for weak magnetic field detection down to 1 Hz .
