Abstract

In order to achieve further lower substrate temperature (Ts) of YBa2Cu3Oy (YBCO) thin films for coated conductor application, we developed low temperature growth (LTG) II technique. In the LTG II technique, a c-axis oriented (Yb1-xNdx)Ba2Cu3Oy thin layer was deposited on MgO substrate as seed layer at low Ts and then YBCO layer was fabricated on the seed layer at the same Ts. As a result, we achieved that the LTG II-YBCO thin films showed complete c-axis orientation at lower Ts than that for obtaining c-axis oriented PLD-YBCO thin films by 15 °C, and showed a high Jc. We discussed the orientation mechanism of the LTG II-YBCO thin film using a simple nucleation model.
