Abstract

In this work, we have undertaken to follow the evolution of the PuCoGa5 superconducting behavior as a function of the damages created by self-radiation effects induced from the Pu-decay. It is shown that the critical temperature is particularly sensitive with ageing. Ageing effects on fundamental parameters such as the lattice parameters of the PuCoGa5 and the electrical resistivity provide some new hints of the unconventional character of the superconductivity in this class of materials
