| Abstract(in English) | We deposited the YBa_2Cu_3O_7 (YBCO) thin films on sapphire substrates using the PLD (pulsed laser deposition) method. The R-sapphire substrate and the CeO_2 buffer layer were utilized in the fabrication. By using the X-ray diffraction measurements, the optimum condition for fabricating the (100) oriented CeO_2 thin film and c-axis oriented YBCO thin film were examined. The typical critical temperature of T_c=85K and critical current density of J_c=1×10^7A/cm^2 (@4.2K) were obtained. We fabricated the LC resonant circuit by forming the YBCO 1-turn coil, and estimated the characteristic of the YBCO thin film from its quality factor measurement. |
