dc.description.abstractThe modification of materials by ion-implantation is a method by which the structure and properties of a material can be altered in a controlled fashion and the study of these modified structures can lead to a better understanding of the parent material. The application to the Held of high temperature superconductors has been present ever since the discovery of the new oxides. In this study, high quality single crystal YBa2 Cu3 O7-δ was implanted separately with several different transition metal ions. The implantation was carried out using a metal vacuum vapour arc (MEVVA) ion source operated at 30kV with an approximate dose of ixlO17 ions/cm2 being applied. The resulting crystals were subsequently annealed in two separate anneal cycles in an oxygen atmosphere at 55O°C for a total of 108 hours. The sample analysis techniques involved the use of Rutherford backscattering spectroscopy (RBS), at both 2 and 3.07MeV, a.c. susceptibility measurements, X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) for compositional, superconductivity, crystal structure and bonding analysis respectively. This paper will report on the results of this study which have shown that the implantation of nickel increased the rate of oxygenation in the near surface region, obtaining a transition temperature of 92°K after only 108 hours anneal time, whereas the implantation of iron was deleterious with a transition temperature of only 78°K reached after the same anneal cycles.en_AU
