Abstract.We report preparation of Y-Ba-Cu-0 thin films by laser evaporation with near-infrared radiation. Pulsed radiation of a Nd-YAG laser (wavelength 1.06 pm) was used for evaporation of material from the surface of a YBa,Cu,O, ceramic sample. Thin films, deposited on A1203 single-crystal substrates, became conductive after a heat treatment in oxygen atmosphere. One of our films, with a room-temperature resistivity of 1 mQ cm, showed onset of superconductivity at 100 K and had T, values of 94-76 K (90%-10%) for the resistive transition. The films were characterised by RES analysis, SEM and x-ray diffraction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
