c-Axis transport properties of YBa2Cu3O7−δ/PrBa2Cu3O7−δ superlattices. — •J.C. Martinez, A. Schattke, G. Jakob, and H. Adrian — Institut f"ur Physik, Johannes Gutenberg-Universit"at, 55099 Mainz
The coupling between the superconducting planes of
YBa2Cu3O7−δ /
PrBa2Cu3O7−δ superlattices has been measured by c-axis
transport
measurements. Series of mesa structures have been patterned on multilayers
with
different periodicities. These results show that only by changing the
thickness
of the superconducting YBa2Cu3O7−δ layers from four to eight
unit cells
it is possible to modify the coupling mechanism from tunneling of
quasi-particles up to Josephson Effect.
