We have studied resistive transitions of a-axis YBa2Cu3O7/a, b-axis PrBa2Cu3O7 superlattices in a magnetic field to investigate the correlation length of vortices along the a-axis direction of YBa2Cu3O7 across an a, b-axis oriented PrBa2Cu3O7 barrier. The correlation of vortices across up to 480 Angstrom of a, b- axis PrBa2Cu3O7 is evidence consistent with long proximity coupling coherence lengths in PrBa2Cu3O7 found in sandwich type YBa2Cu3O7 PrBa2Cu3O7/YBa2Cu3O7 Josephson junctions. Investigation of a-b plane and b-axis transport of undoped and cobalt doped (PrBa2CuO7)-O-3 films suggests that a long localization length along the b-axis of PrBa2Cu3O7 is the origin of this long range proximity coupling, consistent with our vortex coupling experiments and recent theoretical and experimental work based on the electronic structure of PrBa2Cu3O7.
