Study of Deposition of YBa2Cu3O7-x on Cubic Zirconia [PDF]
, 1990 Films of YBa2Cu3O7-x have been grown on (100) cubic zirconia with 8 percent yttria by laser ablation from sintered targets of YBa2Cu3O7-x. The temperature of the zirconia substrate during growth was varied between 700 and 780 °C. The atmosphere during growth was 170 mtorr of oxygen.
