## Description

- description: "Functional materials such as magnetic, thermoelectric, and battery
    materials\r\nhave been revolutionized through nanostructure engineering. However,
    spin\r\ncaloritronics, an advancing field based on spintronics and thermoelectrics
    with\r\nfundamental physics studies, has focused only on uniform materials without\r\ncomplex
    microstructures. Here, we show how nanostructure engineering\r\nenables transforming
    simple magnetic alloys into spin-caloritronic materials\r\ndisplaying significantly
    large transverse thermoelectric conversion properties.\r\nThe anomalous Nernst
    effect, a promising transverse thermoelectric phenomenon for energy harvesting
    and heat sensing, has been challenging to\r\nutilize due to the scarcity of materials
    with large anomalous Nernst coefficients. We demonstrate a remarkable ~ 70% improvement
    in the anomalous\r\nNernst coefficients (reaching ~ 3.7 µVK−1) and a significant
    ~ 200% enhancement\r\nin the power factor (reaching ~ 7.7 µWm−1K−2) in flexible
    Fe-based amorphous\r\nmaterials by nanostructure engineering without changing
    their composition.\r\nThis surpasses all reported amorphous alloys and is comparable
    to single\r\ncrystals showing large anomalous Nernst effect. The enhancement is
    attributed to Cu nano-clustering, facilitating efficient transverse thermoelectric\r\nconversion.
    This discovery advances the materials science of spin caloritronics, opening new
    avenues for designing high-performance transverse\r\nthermoelectric devices for
    practical applications"
