More info

Superconducting bar (Bi-2223) with silver layer on both ends for an easy soldering the current and voltage leads. Suitable as a sample for measuring the critical temperature, recommended measuring current up to 60 mA. Crtitical current at 77 K is a few tens of ampers, (approx. 30 A at zero external magnetic field and approx. 10 A under magnetic field of 25 mT).  Critical temperature (midpoint): 110 K, Critical temperature (zero resistance): 108 K. Resistivity at room temperature: 1

Optional use: measurement of current – voltage characteristics under external magnetic field.
