We followed the evolution of the normal and superconducting properties of Al thin films after each session of various successive oxygen irradiations at ambient temperature. Such irradiated films, similar to the granular ones, exhibit enhanced superco

We explore an analogy between (i) beam attenuation in projectile-electron-loss cross section measurements and (ii) beam-induced exponential decay of magnetization in Ga 1− x Mn x As. Cross sections are experimentally determined to quantify the effe
