Pressure Effects on PuMGa5 Systems (M=Co, Rh, Ir)
We report high-pressure resistivity of PuMGa5 (M 1/4 Co; Rh, Ir) up to 20GPa from 300 down to 1.4 K. For PuCoGa5 and PuRhGa5 superconductivity takes place over the whole pressure domain investigated and a non-Fermi liquid behaviour (rT T1:3) in the normal state is observed. A strong correlation between the temperature–pressure
diagrams of PuCo; RhGa5 and CeCo; IIn5 is inferred. Interestingly, PuIrGa5 does not show superconductivity up to 10 GPa and down to 1.4K but rather develops a Fermi liquid regime.
