Intermetallic compounds with the cubic crystal structure of the PtHg4 type reveal very different ground state properties depending on their chemical content. While solid solution Cr1-xMnxGa4 (0 < x < 0.18) possesses weakly temperature-dependent properties: diamagnetic response and bad metallic behavior, binary MnGa4 exhibits typical metallic properties and is ordered antiferromagnetically already at room temperature. In this work we report on the 69Ga NQR spectroscopy study of intermetallic system Cr1-xMnxGa4 with x = 0 and 0.15 based on ab-initio calculations of electronic density spatial distribution.
