Description

In this work a preliminary pressure-temperature-composition phase diagram for the Ce2Rh(1-x)IrxIn8 heavy-fermions (HF) materials is reported, built from pressure-dependent electrical resistivity (ρ(T)) measurements on single-crystalline samples. Although neither of the two end members is an ambient-pressure SC, a transition to a zero-resistance (ZR) state was found at ambient pressure (TC∼600mK) in a narrow Ir concentration range (around x=0.5). Pressures not higher than 10kbar are sufficient to suppress this ZR state for all measured concentrations, in contrast to the 115 materials
