Abstract
We report the successful synthesis and comprehensive characterization of the kagome metal . This material exhibits a quadratic temperature dependence of resistivity over a broad temperature range, indicative of strong electron-electron interactions, as confirmed by the fact that specific heat measurements with the Kadowaki-Woods ratio lie between those of transition metal and heavy fermion systems. Magnetoresistance measurements reveal a linear magnetic field dependence at low temperatures, while Hall effect measurements display nonlinear behavior describable with a semiclassical two-band model. The angle-dependent magnetoresistance further reveals twofold symmetry. These results collectively suggest an evolution of the band structure within the temperature range of 50–80 K. Magnetic susceptibility measurements indicate paramagnetic behavior with evidence of short-range magnetic correlations emerging near 25 K. Our findings broaden the material landscape of kagome metals and provide a promising platform for exploring correlated electron states and topological quantum phenomena in novel quantum materials.
