A Material View on Extrinsic Magnetic Domain Wall Pinning in Cylindrical CoNi Nanowires Open
Speed and reliability of magnetic domain wall (DW) motion\nare key\nparameters that must be controlled to realize the full potential of\nDW-based magnetic devices for logic and memory applications. A major\nhindrance to this is extrinsic D…

Modeling magnetic-field-induced domain wall propagation in modulated-diameter cylindrical nanowires Open
Domain wall propagation in modulated-diameter cylindrical nanowires is a key phenomenon to be studied with a view to designing three-dimensional magnetic memory devices. This paper presents a theoretical study of transverse domain wall beh…

Bloch-point-mediated topological transformations of magnetic domain walls in cylindrical nanowires Open
Cylindrical nanowires made of soft magnetic materials, in contrast to thin\nstrips, may host domain walls of two distinct topologies. Unexpectedly, we\nevidence experimentally the dynamic transformation of topology upon wall motion\nabove …

We report the imaging of magnetic domains in ferromagnetic CoNiB nanotubes with very long aspect ratio, fabricated by electroless plating.While axial magnetization is expected for long tubes made of soft magnetic materials, we evidence ser…

Imaging magnetic flux-closure domains and domain walls in electroless-deposited CoNiB nanotubes Open
Magnetic nanotubes are predicted to host mag-
\nnetic domains and domain walls with a topology
\ndifferent from that for
\nat elements[1, 2]. Com-
\npared to cylindrical nanowires, reports on mag-
\nnetism of isolated metallic nanotubes a…

Nucleation, imaging, and motion of magnetic domain walls in cylindrical nanowires Open
We report several procedures for the robust nucleation of magnetic domain walls in cylindrical permalloy nanowires. Specific features of the magnetic force microscopy (MFM) contrast of such wires are discussed, to avoid the misinterpretati…
