Abstract

The authors report preparation of Y-Ba-Cu-O thin films by laser evaporation with near-infrared radiation. Pulsed radiation of a Nd-YAG laser (wavelength 1.06 mu m) was used for evaporation of material from the surface of a YBa2Cu3O7 ceramic sample. Thin films, deposited on Al2O3 single-crystal substrates, became conductive after a heat treatment in oxygen atmosphere. One of their films, with a ...

The authors report preparation of Y-Ba-Cu-O thin films by laser evaporation with near-infrared radiation. Pulsed radiation of a Nd-YAG laser (wavelength 1.06 mu m) was used for evaporation of material from the surface of a YBa2Cu3O7 ceramic sample. Thin films, deposited on Al2O3 single-crystal substrates, became conductive after a heat treatment in oxygen atmosphere. One of their films, with a room-temperature resistivity of 1 m Omega cm, showed onset of superconductivity at 100 K and had Tc values of 94-76 K (90%-10%) for the resistive transition. The films were characterised by RBS analysis, SEM and X-ray diffraction.
