Y1-xGdxBa2Cu3O7-y film with BaZrO3 was fabricated on CeO2 buffered LaMnO3/ion beam assisted deposition MgO/Gd2Zr2O7/Hastelloy C276TM substrates by the trifluoroacetates metal organic deposition process, whose microstructural and elemental analyses were performed by transmission electron microscopy. Y1-xGdxBa2Cu3O7-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)2Cu2O5, CuO and BaZrO3. (Y,Gd)2Cu2O5 and CuO precipitates were heterogeneously dispersed in the Y1-xGdxBa2Cu3O7-y matrix with their sizes ranging between 100 and 200 nm, and BaZrO3 precipitates were uniformly dispersed with their sizes ranging between 10 and 20 nm. Electron tomography with elemental information was performed further to reveal the threedimensional information of BaZrO3 precipitates.
