Abstract: We report pressure and temperature dependent electrical resistivity measurements in the Ce2 Rh1 - x Irx In8 alloys. Our results revealed two phases with zero resistance. One of these phases is induced by pressure, occurring for a range of compositions situated near the Rh-rich extreme, consistent with the behavior observed for the pure Ce2 RhIn8 compound. The second transition occurs for intermediate concentrations (x ∼ 0.5 - 0.7), and in sharp contrast with the first transition, is progressively eliminated by the application of pressure. We compare the findings in the Ce2 Rh1 - x Irx In8 alloys to its related CeRh1 - x Irx In5, discussing how the occurrence of the superconducting phases may become unfavorable for the bi-layer alloys due to higher dimensionality and stronger disorder. © 2007 Elsevier B.V.
