We have carried out electrical resistivity ρ and AC-susceptibility χAC measurements on YbInCu4 under pressure. For pressures above 2.49 GPa, the first-order valence transition is completely suppressed and a clear peak appears in χAC with a small kink in ρ at TM = 2.4 K. The χAC peak is easily diminished by applying low magnetic fields and disappears above ∼ 500 Oe. The characteristic behavior of χAC at TM can generally be ascribed to the onset of long-range ferromagnetic ordering and, therefore, the ground state of the pressure-stabilized phase of YbInCu4 is most probably a ferromagnetically ordered state.
