Abstract:
Y 1-x Gd x Ba 2 Cu 3 O 7-y film with BaZrO 3 was fabricated on CeO 2 buffered LaMnO 3 /ion beam assisted deposition MgO/Gd 2 Zr 2 O 7 /Hastelloy C276 TM substrates by the trifluoroacetates metal organic deposition process, whose microstructural and elemental analyses were performed by transmission electron microscopy. Y 1-x Gd x Ba 2 Cu 3 O 7-y film with the thickness about 700 nm was found composed of c-axis oriented grains and large numbers of randomly oriented precipitates, such as (Y,Gd) 2 Cu 2 O 5 , CuO and BaZrO 3 . (Y,Gd) 2 Cu 2 O 5 and CuO precipitates were heterogeneously dispersed in the Y 1-x Gd x Ba 2 Cu 3 O 7-y matrix with their sizes ranging between 100 and 200 nm, and BaZrO 3 precipitates were uniformly dispersed with their sizes ranging between 10 and 20 nm. Electron tomography with elemental information was performed further to reveal the three-dimensional information of BaZrO3 precipitates.
