Query: Charge and Spin Supercurrents in Magnetic Josephson Junctions with Spin
  Filters and Domain Walls   We analyze theoretically the influence of domain walls (DWs) on the DC
Josephson current in magnetic superconducting S$_{m}$/Fl/F/Fl/S$_{m}$
junctions. The Josephson junction consists of two "magnetic" superconductors
S$_{m}$ (superconducting film covered by a thin ferromagnetic layer), spin
filters Fl and a ferromagnetic layer F with or without DW (DWs). The spin
filters Fl allow electrons to pass with one specific spin orientation, such
that the Josephson coupling is governed by a fully polarized long-range triplet
component. In the absence of DW(s), the Josephson and spin currents are nonzero
when the right and left filters, Fl$_{r,l}$, pass electrons with equal spin
orientation and differ only by a temperature-independent factor. They become
zero when the \textbf{spins} of the triplet Cooper pairs passing through the
Fl$_{r,l}$ have opposite directions. Furthermore, for the different chiralities
of the injected triplet Cooper pairs the spontaneous currents arise in the
junction yielding a diode effect. Once a DW is introduced, it reduces the
critical Josephson current $I_{c}$ in the case of equal spin polarization and
makes it finite in the case of opposite spin orientation. The critical current
$I_{c}$ is maximal when the DW is in the center of the F film. A deviation of
the DW from the center generates a force that pushes the DW to the center of
the F film. In addition, we consider the case of an arbitrary number $N$ of
DW's, with the case $N=2$ corresponding to a model system for a magnetic
skyrmion.
