The fragile nature of itinerant magnetism can be exploited using non-thermal parameters to study quantum criticality. The recently discovered quantum critical point (QCP) in the Sc-doped (hole-like doping) itinerant antiferromagnet TiAu (Ti1-xScxAu) raised questions about the effects of the crystal and electronic structures on the overall magnetic behavior. In this study, doping with V (electron-like doping) in Ti1-xVxAu introduces chemical disorder which suppresses antiferromagnetic order from TN = 36 K for x = 0 down to 10 K for x = 0.15, whereupon a solubility limit is reached. Signatures of non-Fermi-liquid behavior are observed in transport and specific heat measurements similar to Ti1-xScxAu, even though Ti1-xVxAu is far from a QCP for the accessible compositions x ≤ 0.15.
