 Abstract: We investigated the non-monotonous evolution of superconductivity with pressure (P)(P) in a single crystal of CeCu2(Si0.9Ge0.1)2CeCu2(Si0.9Ge0.1)2 (P=0P=0: antiferromagnetic order at View the MathML sourceTN≈1.2K, superconductivity at View the MathML sourceTc≈0.35K). Electrical resistivity measurements were performed at low temperatures View the MathML sourceT⩾50mK under nearly hydrostatic pressure conditions View the MathML source(0<P<4.5GPa). The existence of two distinct superconducting domes is observed in the T–PT–P phase diagram, one at View the MathML source0<P<2.2GPa and the other at View the MathML source2.2<P<4.5GPa. Surprisingly, our preliminary data suggest that the T–PT–P phase diagram is more rich in structure than reported previously.
