## Description

- description: Sm-Co bulk alloys are well known permanent magnets having large remanent
    magnetizations and coercive forces and are widely used in many industrial products.
    Recently, a large transverse thermoelectric conversion was observed for SmCo5
    over a wide temperature range in the absence of magnetic fields. The large anomalous
    Nernst coefficient (ANC) was also confirmed by the first-principles density functional
    theory (DFT) calculations. In this study, we predicted further enhancement of
    the ANC by including Ni in Co site of SmCo5. We showed that the ANC of Sm(Co1-xNix)5
    increases with increasing the Ni ratio and takes the maximum value αxy = 11.3
    A K-1 m-1 around x = 0.08 at 300 K, which is about 77% enhancement of αxy = 6.4
    A K-1 m-1 in SmCo5. We clarified that the band-proximity points near the nodal
    line of Sm(Co0.92Ni0.08)5 are the main contributing factor to the large Berry
    curvature, providing the steep slope of the energy dependence in the anomalous
    Hall conductivity around the Fermi energy.
