Abstract

We have carried out electrical resistivity ρ and AC-susceptibility χ_AC 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 χ_AC with a small kink in ρ at T_M = 2.4 K. The χ_AC peak is easily diminished by applying low magnetic fields and disappears above ∼ 500 Oe. The characteristic behavior of χ_AC at T_M 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.
