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 TN = 2.7 K at ambient pressure decreases with increasing pressure p and disappears at a critical pressure pc ≃ 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 pc.
