## Description

- description: Applying a magnetic field to a solid changes its thermal-transport
    properties. Although such magneto-thermal-transport phenomena are usually small
    effects, giant magneto-thermal resistance has recently been observed in spintronic
    materials and superconductors, opening up new possibilities in thermal management
    technologies. However, the thermal conductivity conventionally changes only when
    a magnetic field is applied due to the absence of nonvolatility, which limits
    potential applications of thermal switching devices. Here, we report the observation
    of nonvolatile thermal switching that changes the electron thermal conductivity
    when a magnetic field is applied and retains the value even when the field is
    turned off. This unconventional magneto-thermal switching arises in commercial
    Sn-Pb solders and is realized by phase-separated superconducting states and resultant
    nonuniform magnetic flux distributions. This result confirms the versatility of
    the observed phenomenon and aids the development of active solid-state thermal
    management devices.
