초록정보

$YBa_2Cu_3O_x$ thick films were fabricated on MgO single crystal substrates to induce the preferred orientation by screen printing of powder mixture of $Y_2BaCuO_5$ (211), $BaCuO_2$ (011) and CuO, partial melting and controlled cooling process. The precursor powders were prepared with the solid state sintering and planetary milling, and the powder mixture was prepared with planetary milling. The superconductivity of mixed $YBa_2Cu_3O_x$ powder was evaluated with sintering and $O_2$ annealing at different temperatures. The paste of the powder mixture was fabricated using a standard paste making process, and the thick films of few ten microns were fabricated multiple screen printing. The films were heated at different temperatures from 950 to 1050℃ and cooled down at different cooling schedules. To reduce a possible low temperature reaction, the sample was put into the furnace maintained at the objective temperature. The microstructure and phases of the thick films fabricated with different temepratures, different thickness, different cooling schedules and pressure were analyzed using XRD, pole figure, phi scan, rocking curve, SEM, EDXS and polarizing microscope. The superconducting properties were analyzed using four point probe method.
