説明:

We phenomenologically formulate the appearance of transverse magneto-thermoelectric phenomena, i.e., the anomalous Nernst effect and Seebeck-driven anomalous Hall effect, in artificially tilted multilayers consisting of magnetic and thermoelectric materials, where the off-diagonal Seebeck effect originally exists due to the anisotropic composite structure. Because the contributions of the anomalous Nernst, Seebeck-driven anomalous Hall, and off-diagonal Seebeck effects to transverse thermopower have different artificial structure dependences with each other, the total thermoelectric performance maximizes by optimizing the structure to balance these effects. We confirm the appearance of these thermoelectric effects by performing a finite element analysis of transverse thermoelectric fields in artificially tilted multilayers consisting of ferromagnetic Co2MnGa Heusler alloy and thermoelectric semiconductor Bi2Te3. This work will be a guideline to design the optimum structural parameters for superior transverse thermoelectric performance through the hybridization of spin- and magnetism-related thermoelectric phenomena in artificially tilted multilayers.
