    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.
