Magneto-thermal switching using superconducting metals and alloys
Superconductors exhibit low thermal conductivity (κ) due to the suppression of electronic thermal conduction in the superconducting states with Cooper pairs. This change in κ enables superconductors to function as magneto-thermal switches (MTS). In this article, we review MTS behavior in pure-metal...

| Summary: | Superconductors exhibit low thermal conductivity (κ) due to the suppression of electronic thermal conduction in the superconducting states with Cooper pairs. This change in κ enables superconductors to function as magneto-thermal switches (MTS). In this article, we review MTS behavior in pure-metal superconductors, phase-separated superconductors, and alloy-based superconductors. A large switching ratio can be achieved using high-purity superconducting metals. Nonvolatile MTS is observed in phase-separated superconductors, where the flux-trapping states are crucial for the nonvolatile MTS. |
