## Abstract

We propose conceptually novel thermopile structures for the anisotropic magneto-Peltier effect (AMPE) to enhance its heating/cooling power. The cross-shaped thermopile, one of the representative AMPE-based thermopile structures, consists of four L-shaped ferromagnetic metals arranged in a cross-shaped configuration, which allows concentration of the AMPE-induced temperature modulation at the center of the cross structure. The AMPE-based thermopile does not require the use of any complicated junctions comprising different materials, enabling the design of compact and versatile temperature controllers for nanoscale devices.
