Query: Multiple 0 - pi transitions in SIFS Josephson tunnel junctions   We report on experimental studies of superconducting coupling through a thin
Ni76Al24 film. A new patterning process has been developed, which allows in
combination with the wedge shaped deposition technique the in situ deposition
of 20 single Nb/Al/Al2O3/Ni3Al/Nb multilayers, each with its own well defined
Ni3Al thickness. Every single multilayer consists of 10 different sized
Josephson junctions, showing a high reproducibility and scaling with its
junction area. Up to six damped oscillations of the critical current density
against F-layer thickness were observed, revealing three single 0-pi
transitions in the ground state of Josephson junctions. Contrary to former
experimental studies, the exponential decay length is one magnitude larger than
the oscillation period defining decay length. The theoretical predictions based
on linearized Eilenberger equations result in excellent agreement of theory and
experimental results.
