We have fabricated vertical YBa 2Cu3O7−x/PrBa 2Cu3O7−x/YBa 2Cu3O7−x (YBCO/PBCO/YBCO) Josephson junctions using in-plane aligned a-axis oriented YBCO multilayers on (100) LaSrGaO4(LSGO). The Tc's of the device electrodes are typically greater than 80 K. Josephson coupling is observed for barrier thickness up to 800 A(ring). Strong nonlinear I–V characteristics arising from the properties of PBCO are observed for thicker barrier devices. Chip to chip spread in the device characteristics may be intrinsically due to the PBCO barrier. © 1996 American Institute of Physics.
