Here, we report the pressure dependence of the Néel temperature TN up to P ≈ 27 GPa for the recently discovered itinerant antiferromagnet (IAFM) TiAu. The TN(P) phase boundary exhibits unconventional behavior in which the Néel temperature is enhanced from TN ≈ 33 K at ambient pressure to a maximum of TN ≈ 35 K occurring at P ≈ 5.5 GPa. Upon a further increase in pressure, TN is monotonically suppressed to ~22 K at P ≈ 27 GPa. We also find a crossover in the temperature dependence of the electrical resistivity ρ in the antiferromagnetic (AFM) phase that is coincident with the peak in TN(P), such that the temperature dependence of ρ = ρ0 + AnTn changes from n≈3 during the enhancement of TN to n ≈ 2 during the suppression of TN. Based on an extrapolation of the TN(P) data to a possible pressure-induced quantum critical point, we estimate the critical pressure to be Pc ≈ 45 GPa.
