Abstract

Oxygen-ion implantation effect in pellets and films of Y₁Ba₂Cu₃O_y superconductor is reported here. Oxide pellets implanted with 100 keV 5 × 10¹⁶O⁺₂/cm² were annealed in a flow of pure Ar gas at 850 °C. Oxygen-ion-implanted pellets showed the onset of superconductivity at 90 K, but unimplanted pellets became insulators by the same process. Dose dependence of the resistivity at 100 K is also reported for phosphorus-implanted films after furnace annealing. The normal resistivity of Y₁Ba₂Cu₃O_y films decreased, and increases in T_c were found at certain implanted phosphorus concentrations.
