| contents | Kagome metals gain attention as they manifest a spectrum of quantum phenomena, including superconductivity, charge order, frustrated magnetism, and intertwined correlated states of condensed matter. With regard to electronic band structure, several of the them exhibit non-trivial topological characteristics. Here, we present a thorough investigation on the growth and the physical properties of single crystals of Ni3In2S2 which is established to be a Dirac nodal line Kagome metal. Extensive characterization is attained through temperature and field-dependent resistivity, angle-dependent magnetoresistance and specific heat measurements. In most metals, the Fermi liquid behaviour is mostly restricted to a narrow range of temperature. In Ni3In2S2, this characteristic feature has been observed for an extensive temperature range of 82 K. This is attributed to the strong electron-electron correlation in the material. Specific heat measurements reveal a high Kadowaki-Woods ratio which is in good agreement with strongly correlated systems. Almost linear positive magnetoresistance follows the conventional Kohler scaling which depicts the applicability of semi-classical theories. The angle-dependent magneto-resistance been explained using the Voigt-Thomson formula. Furthermore, de-Haas van Alphen oscillations are observed in magnetization vs. magnetic field measurement which shed light on the topological features in the Shandite Ni3In2S2. |
