## Description

- description: 'Transverse thermoelectric conversion holds significant potential in
    addressing complex challenges faced by classical Seebeck/Peltier modules. A promising
    transverse thermoelectric phenomenon is the anomalous Nernst effect originating
    from nontrivial band structures in magnetic topological materials. However, the
    currently reported performance of the anomalous Nernst effect in topological materials,
    e.g., Co2MnGa, remains insufficient for practical thermoelectric applications.
    Here, we unveil an unconventional availability of the anomalous Nernst effect
    by integrating magnetic topological materials into artificially tilted multilayers,
    known to exhibit the structure-induced transverse thermoelectric conversion due
    to the off-diagonal Seebeck effect. Our experiments reveal that the transverse
    thermoelectric performance in Co2MnGa-based artificially tilted multilayers is
    improved through the hybrid action of the anomalous Nernst and off-diagonal Seebeck
    effects, with the magnetization-dependent performance modulation being one order
    of magnitude greater than the performance achievable with the anomalous Nernst
    effect alone. This synergy underscores the importance of hybrid transverse thermoelectric
    conversion and paves a way for advancing thermoelectric applications using magnetic
    materials. '
