Description
The method of low pressure annealing was adopted to enhance the removal of HF gas from the surface of the MOD-YBCO films, hence to increase the growth rate of YBCO films. In this work, the total pressure in annealing process was varied from 700 Torr to 1 Torr and its effect on the growth of YBCO films was compared with atmospheric pressure. The lower pressure was found effective to increase the growth rate and to control the pore size of the YBCO films in MOD method. A fast growth of MOD-YBCO films was realized with high critical current density over 1 MA/cm2 using low pressure annealing. Large pores, usually observed at atmospheric pressure in MOD method, disappeared and also the number of pores was reduced
