✦ Synopsis

A Kronig Penney periodic pair potential model is proposed for YBa 2Cu 3 0, with the pair potential only depending on the coordinate parallel to the c-axis. Numerical results for the 3-D density of states are compared with existing tunneling data. As a main result, oscillations in the high energy tunneling characteristics can be attributed to energy bands resulting from the periodic potential.

The superconductivity of YBaQtsO,/PrBarCu,O, (YBCO/PBCO) multilayers has been studied under parallel and perpendicular magnetic fields H ranging from 0 to 7 T. The resistive transitions of the selected [YBCO/PBCO]s of 48 A/ 100 A and 48 A/ 12 A have been investigated in detail. For both systems the
