Giant magneto-thermal resistance has been recently observed in spintronic materials and superconductors, with exciting prospects in thermal management technologies. Here, nonvolatile thermal switching by magnetic field is demonstrated in commercial Sn-Pb solders, with electron thermal conductivity retaining its value even when the field is turned off.
