NUCLEAR MICROPROBE CHARACTERIZATION OF SU PERCONDUCTOR OXIDES

Nuclear microprobe characterization of superconductor oxides. The loca l elemental characterization (in a few mum3) of superconductor oxides may be performed by means of the nuclear microprobe. According to the nature of the ions of the beam, protons, deuterons or alphas, and to t he type of the measured interactions, X rays, backscattered ions or nu clear reactions, complementary informations may be obtained, mean comp ositions, depth profiles or local crystallinity. The main limitation o f the performances of the method is the modification induced in the sa mple by the microbeam, due to a high level of local energy deposition.
