Abstract :
High-T/sub c/ superconducting thick films were prepared using a method combining grain shape alignment and low magnetic field alignment. The superconducting films with a thickness of about 100 mu m exhibiting T/sub c/(zero) higher than 90 K were successfully obtained. X-ray diffraction data showed the thick Y/sub 1/Ba/sub 2/Cu/sub 3/O/sub z/ film having grain alignment. The orientation along the c-axis is pronounced with an increase in the heat-treatment temperature and time in magnetic field.<>
