| contents | Kagome materials are known to be an ideal platform that hosts a plethora of interesting phases such as topological states, electronic correlation, and magnetism, owing to their unique band structure and geometry. We report magnetotransport measurement in Kagome metal Yb$_{0.5}$Co_3Ge$_3$ as a function of pressure. Below $\sim25^\circ$ K the temperature dependence of resistance shows an upturn that is accompanied by a strong negative magnetoresistance, which could be attributed to Kondo effect. Upon pressurization above 1 GPa the resistance shows a reduction as a function of temperature below $4^\circ$ K, along with a further enhanced negative magnetoresistance. This might indicate an onset of a pressure-induced Kondo coherence effect. |
