Thermal imaging of the spin Peltier effect

Ken-ichi UCHIDA1

In the field of spin caloritronics, the interplay between spin and heat currents has been extensively studied from the viewpoints of the fundamental physics and thermoelectric applications. One of the emerging topics in this field is the spin Peltier effect (SPE), which refers to the heat-current generation as a result of spin-current injection in magnetic junctions. Recently, by means of the lock-in thermography technique, we successfully visualized the temperature modulation induced by the SPE and revealed the characteristic distribution of spin-current-induced heat sources. In this article, we review the thermal imaging of the SPE and show the usefulness of the lock-in thermography technique for spin-caloritronics research.
