description | YBa[sub 2]Cu[sub 3]O[sub 7[minus][delta]] of (YBCO) was produced through oxidation of a 1:2:3 mixture of YI[sub 3], BaI[sub 2]2H[sub 2]O, and CuI solids. TGA of the iodides revealed low-temperature oxidation below 600[degrees]C of the iodide precursors to the oxides. Thin oriented films of orthorhombic YBCO were prepared by multiple spin coating, drying, and oxidizing solutions of the same solids mixture in acetonitrile/ethanol on a SrTiO[sub 3] single crystal. Confirmation of bulk and film structures were made with the aid of X-ray diffractograms, scanning electron and optical microscopy, and resistivity measurements. Typical zero resistance' behavior at 90 K was observed for the iodide precursor derived YBCO. |
