- Created High-Temperature Superconductor Bar or Tape (part): "Provides a known transition (Bi-2223 near 108 to 110 K, REBCO near 90 K) for validating four-probe resistance against temperature. Choose a bar or tape with solderable silver ends and a stated Tc, and ask REBCO makers for a short length without copper stabilizer, which masks resistance above Tc."
