Critical current control in ferromagnetic proximity junctions by magnetization and spin injection — •Lukas Kammermeier and Elke Scheer — Universität Konstanz, Konstanz, Germany
We exploit the inverse proximity effect of a ferromagnet on a
superconductor to locally suppress the superconductivity in a thin wire
and thereby create a Josephson junction.
We show that we can control
the critical current Ic over a wider range by manipulating the
magnetization state of the ferromagnet, possibly sensitive to single
magnetic domains in proximity to the constriction. Additionally, the
efficiency of spin injection by running a current from the
spin-polarized ferromagnet into the junctions constriction will be
presented.
