## Description

- description: We report a systematic evaluation of the effects of post-deposition
    annealing temperature and structural ordering on the anomalous Nernst effect (ANE)
    in Fe2CoSi (FCS) Heusler alloy thin films. The study reveals that amorphous/disordered
    FCS films exhibit a larger anomalous Nernst coefficient (SANE) compared to their
    crystalline counterparts, in stark contrast to conventional Co-based Heusler alloys,
    which typically show maximum SANE in highly ordered structures. Furthermore, as
    a strategy for enhancing transverse thermoelectric properties, we explore (FCS)100−xPtx
    composite alloy films by systematically varying the Pt concentration and optimizing
    the composition. This method effectively enhances the transverse thermoelectric
    performance of the FCS-based alloys. Our findings offer valuable insights for
    the design and development of next-generation high-performance ANE materials.
