Query: Nanowire magnetic force sensors fabricated by focused electron beam
  induced deposition   We demonstrate the use of individual magnetic nanowires (NWs), grown by
focused electron beam induced deposition (FEBID), as scanning magnetic force
sensors. Measurements of their mechanical susceptibility, thermal motion, and
magnetic response show that the NWs posses high-quality flexural mechanical
modes and a strong remanent magnetization pointing along their long axis.
Together, these properties make the NWs excellent sensors of weak magnetic
field patterns, as confirmed by calibration measurements on a micron-sized
current-carrying wire and magnetic scanning probe images of a permalloy disk.
The flexibility of FEBID in terms of the composition, geometry, and growth
location of the resulting NWs, makes it ideal for fabricating scanning probes
specifically designed for imaging subtle patterns of magnetization or current
density.
