Auto-ionic - microscopy analysis of radiation defects in Y-Ba-Cu-O monocrystals

Defective structure of YBa2Cu3O7-x monocrystal samples with 1-2-3-type structure, irradiated by Ar+ ions with 35 keV energy, is studied. All samples were observed during the first stage by means of ion microscope, whereat their apexes were formed through the field evaporation. Thereafter the samples were irradiated at a facility for ion implantation by Ar+ ions. This was followed by repeated analysis of samples in auto-ion microscope, whereby the obtained microscopic images were registered by photographing from fluorescent screen as well as by means of television camera, connected with the IBM-type computer. Program package was applied for further machine processing. 21 refs., 2 figs
