<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">We present initial investigation of the superconductor-ferromagnet-superconductor (SFS) heterostructures of nanometer dimensions prepared by the gallium focused ion beam (FIB) technology.

SFS weak link junctions require dimensions of the weak link connection in the range of nanometer size realizable by FIB patterning.
