Abstract
Surface images of superconducting phase YBa2Cu3O6.90 and YBa2Cu3O6.15 compound have been obtained using FIM technique. The ion image is shown to be produced by yttrium atoms mainly. The superconductor crystal lattice defects have been examined. The ion contrast given by a twin boundary is discussed taking into account the type of imaging atoms.
