説明:

We report the observation of a spatial allocation of Peltier-effect-induced temperature modulation through the anomalous Hall effect (AHE) in a hybrid system comprising a magnetic metal and a thermoelectric semiconductor. AHE in the magnetic metal generates a transverse electric field perpendicular to the applied bias voltage, inducing charge injection into the thermoelectric layer via the closed circuit and resultant heating and cooling generation in a transverse geometry. Using an active thermal imaging technique, lock-in thermography, we visually extract the AHE-originating thermal contribution from other magneto-thermoelectric effects. Such heat allocation enables flexible design of transverse thermoelectric conversion, providing a pathway toward on-chip thermal management and selective temperature control at designated regions.
