Abstract
We have fabricated vertical a2Cu3O7-x/PrBa2Cu3O7-x/YBa2Cu3O7-x(YBCO/PB CO/YBCO) Josephson junctions using in-plane aligned a-axis oriented YB CO multilayers on (100) LaSrGaO4(LSGO). The T-c's of the device electr odes are typically greater than 80 K. Josephson coupling is observed f or barrier thickness up to 800 Angstrom. Strong nonlinear I-V characte ristics arising from the properties of PBCO are observed for thicker b arrier devices. Chip to chip spread in the device characteristics may be intrinsically due to the PBCO barrier. (C) 1996 American Institute of Physics.
