|Abstract:||Low-temperature accumulation and annealing experiments, in conjunction with electrical resitivity and critical current density measurements, were used to study the ageing of the actinide superconductor PuCoGa5. These measurements reveal that 2-nm–sized nonsuperconducting point-like regions are the main damages formed during room temperature ageing; smaller point-like defects are irrelevant to transport properties. Defect sizes and densities deduced from experiment agree with Transmission Electron Microscopy observations.|
