SUPERCONDUCTING YBCO AND BSCCO THIN FILMS PREPARED BY PULSED LASER DEPOSITION AND POST ANNEALING
Keywords:
BSCCO, Pulsed Laser Deposition, superconducting thin films, YBCOAbstract
The YBCO and BSCCO superconducting thin films have been grown on MgO (100)
by pulsed laser deposition from a sintered YBa2Cu3Oy and Bi1.6Pb0.4Sr2Ca2Cu3Oy
target. Post annealing after deposition at 850OC in 30 minutes resulted in BSCCO
superconducting films with zero resistance at 52 K. YBCO film annealed for 2 hours
is non-superconducting but it is improved by increasing the time to 4 hours and 5
hours at 920OC . X-Ray diffraction pattern shows a predominance of 001 peaks for
BSCCO film and no improvement of crystallinity after annealed for YBCO film.
