Abstract

We have studied the effect of pressure on the electrical resistivity of the antiferromagnet CeMg₂Cu₉ which crystallizes in the hexagonal structure. The structure is built up of alternating MgCu₂ Laves-type and CeCu₅-type layers along the [0001] direction. The Néel temperature T_N = 2.7 K at ambient pressure decreases with increasing pressure p and disappears at a critical pressure p_c ≃ 2.5 GPa. Correspondingly, the residual resistivity ρ₀ and the coefficient A in a Fermi-liquid relation ρ = ρ₀ + AT² are found to have maximum values around p_c.
