Observation of quantum criticality in antiferromagnetic based (Ce1−xYx)2Ir3Ge5 Kondo-Lattice system

•The chemical substitution dependencies of the three power law parameters have very similar behavior.•The minimum n exponent, maximum A coefficient, and ρo residual resistivity are at the same critical concentration xcr, expecting the sign for QCP in a non-Fermi Liquid (nFL) region.•Above xcr, the A values drop abruptly and the n values increase only slightly, indicating a transition from strongly to weakly correlated regime near the critical concentration xcr.
