      abstract     = {Investigating the local micromagnetic structure of
                      ferromagnetic nanowires (NWs) at the nanoscale is essential
                      to study the structure–property relationships and can
                      facilitate the design of nanostructures for technology
                      applications. Herein, we synthesized high-quality iron and
                      cobalt NWs and investigated the magnetic properties of these
                      NWs using off-axis electron holography. The Fe NWs are about
                      100 nm in width and a few micrometers in length with a
                      preferential growth direction of [100], while the Co NWs
                      have a higher aspect-ratio with preferential crystal growth
                      along the [110] direction. It is noted that compact
                      passivation surface layers of oxides protect these NWs from
                      further oxidation, even after nearly two years of exposure
                      to ambient conditions; furthermore, these NWs display
                      homogeneous ferromagnetism along their axial direction
                      revealing the domination of shape anisotropy on magnetic
                      behavior. Importantly, the average value of magnetic
                      induction strengths of Fe NWs (2.07 {±} 0.10 T) and Co NWs
                      (1.83 {±} 0.15 T) is measured to be very close to the
                      respective theoretical value, and it shows that the surface
                      oxide layers do not affect the magnetic moments in NWs. Our
                      results provide a useful synthesis approach for the
                      fabrication of single-crystalline, defect-free metal NWs and
                      give insight into the micromagnetic properties in
                      ferromagnetic NWs based on the transmission electron
                      microscopy measurements.},
