Our group recently demonstrated that the ground-state phase difference across such a junction with carefully chosen layer thicknesses could be controllably toggled between zero and $\\pi$ by switching the relative magnetization directions of the two layers between the antiparallel and parallel configurations. However, several technological issues must be addressed before those junctions can be used in a large-scale memory. Many of these issues can be more easily studied in single junctions,","authors_text":"Bethany M. Niedzielski, Joseph A. Glick, Jr., Norman O. Birge, R. Loloee, T.J. Bertus, W. P.
