摘要：

We have demonstrated the viability of in situ ultrasonic spray pyrolysis (USP) for coating highly aligned YBa2CU3O7-x conductors some four years ago. In this work we demonstrate further improvement of these conductors by deposition of more highly concentrated precursor solution. Highly biaxially aligned, similar to1 mum YBCO thick films were deposited in situ on single crystal (10 0) SrTiO3 from nitrate precursor solutions, The typical growth rate was 0.3 mum/min. J(c)'s were similar to5 x 10(5) A/cm(-2) at 77 K. At 40 K, magnetic measurements indicated good grain connectivity up to 7 T, although weaker connectivity was observed at 77 K.
