Abstract

Ion beam mixing in Cu-Bi bilayered samples was studied using measurements of the superconducting transition temperature, Tc, backscattering analysis and electron microscopy. All measurements could be performed in situ, without warming above the irradiation temperature. Irradiation of the bilayered samples with energetic Kr+ at 10 K induces an amorphous phases which is also superconducting below ∼ 5.2. On annealing, complete recrystallization did not occur until room temperature. The backscattering results revealed that irradiation at 10 K causes significant interdiffusion of Cu and Bi but that at 295 K, there is essentially no mixing.
