Abstract

다층의 산화물 박막으로 이루어진 coated conductor의 제조를 위하여 각층의 증착조건이 최적화되어야 한다. 가공/열처리를 통하여 2축배향성을 가지는 Ni 금속 기판위에 $Y_2O_3$, YSZ, $CeO_2$ 등의 산화물 완충층을 증착한 후 초전도층인 YBCO를 증착하였다. 12도와 8도의 in-plane fwhm (full width at half maximum)과 out-of-plane fwhm을 가지는 Ni 기판을 이용하여 13도와 4.5도의 in-plane 및 out-of-plane fwhm을 가지는 YBCO coated conductor를 제조하였다. 임계온도 (Tc), 임계전류 (Ic), 및 임계전류밀도 (Jc) 는 각각 84K, 3.3A, 및 $310,000\;A/cm^2$ 이었다.
