## Description

- description: Transverse thermoelectric conversion phenomena including the anomalous
    Ettingshausen effect (AEE) and anomalous Nernst effect (ANE) in magnetic materials
    have been actively investigated to realize versatile cooling and energy harvesting
    technologies, respectively. However, further improvement of thermoelectric performance
    of AEE and ANE is still required, and most research efforts have focused on material
    exploration. Here, a new approach to improve the transverse thermoelectric conversion
    performance through interface engineering is reported by focusing on the transverse
    thermoelectric phenomena that output heat currents. A longitudinal charge current
    in a ferromagnetic metal Ni/nonmagnetic insulator Bi2WO6 hybrid-structure induces
    a larger transverse heat current than that of AEE in a Ni single-layer. It is
    indicated that the enhancement of the transverse thermoelectric conversion is
    due to the generation of a heat current concomitant with a spin current induced
    at the Ni/Bi2WO6 interface. This finding demo
