Micromagnetics of magnetic chemical modulations in soft-magnetic cylindrical nanowires
L. Álvaro-Gómez, S. Ruiz-Gómez, C. Fernández-González +17
We analyze the micromagnetics of short longitudinal modulations of a high-magnetization material in cylindrical nanowires made of a soft-magnetic material of lower magnetization su…
A material view on extrinsic magnetic domain wall pinning in cylindrical CoNi nanowires
M. Schøbitz, O. Novotny, B. Trapp +7
Speed and reliability of magnetic domain wall (DW) motion are key parameters that must be controlled to realize the full potential of DW-based magnetic devices for logic and memory…
Direct observation of homogeneous cavitation in nanopores
V. Doebele, A. Benoit-Gonin, F. Souris +8
We report on the evaporation of hexane from porous alumina and silicon membranes. These membranes contain billions of independent nanopores tailored to an ink-bottle shape, where a…
Observation of Large Unidirectional Rashba Magnetoresistance in Ge(111)
T. Guillet, C. Zucchetti, Q. Barbedienne +8
Relating magnetotransport properties to specific spin textures at surfaces or interfaces is an intense field of research nowadays. Here, we investigate the variation of the electri…
Fast domain walls governed by Œrsted fields in cylindrical magnetic nanowires
M. Schöbitz, A. De Riz, S. Martin +14
Since its proposal, the idea to vastly increase data storage density with a magnetic non-volatile 3D shift-register has sustained interest in current-induced domain wall (DW) motio…
Measurement of anisotropic thermal conductivity of a dense forest of nanowires using the 3 method
Dhruv Singhal, Jessy Paterson, Dimitri Tainoff +7
The 3 method is a dynamic measurement technique developed for determining the thermal conductivity of thin films or semi-infinite bulk materials. A simplified model is often app…
Bloch-point-mediated topological transformations of magnetic domain walls in cylindrical nanowires
Olivier Fruchart, A Wartelle, B Trapp +11
Cylindrical nanowires made of soft magnetic materials, in contrast to thin strips, may host domain walls of two distinct topologies. Unexpectedly, we evidence experimentally the dy…
Flux-closure domains in high aspect ratio electroless-deposited CoNiB nanotubes
Michal Staňo, Sandra Schaefer, Alexis Wartelle +13
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…
Nucleation, imaging and motion of magnetic domain walls in cylindrical nanowires
S Da Col, S Jamet, M Staňo +5
We report several procedures for the robust nucleation of magnetic domain walls in cylindrical permalloy nanowires. Specific features of the magnetic force microscopy contrast of s…
Quantitative analysis of shadow X-ray Magnetic Circular Dichroism Photo-Emission Electron Microscopy
S. Jamet, S. Da Col, N. Rougemaille +10
Shadow X-ray Magnetic Circular Dichroism Photo-Emission Electron Microscopy (XMCD-PEEM) is a recent technique, in which the photon intensity in the shadow of an object lying on a s…
Broadband Setup for Magnetic-Field-Induced Domain Wall Motion in Cylindrical Nanowires
Alexis Wartelle, Christophe Thirion, Raja Afid +9
In order to improve the precision of domain wall dynamics measurements, we develop a coplanar waveguide-based setup where the domain wall motion should be triggered by pulses of ma…
Ordered arrays of magnetic nanowires investigated by polarized small-angle neutron scattering
Thomas Maurer, Sébastien Gautrot, Frédéric Ott +4
Polarized small-angle neutron scattering (PSANS) experimental results obtained on arrays of ferromagnetic Co nanowires ( nm) embedded in self-organized alumina (Al$_{2}…
Observation of Bloch-point domain walls in cylindrical magnetic nanowires
Sandrine Da Col, Segolene Jamet, Nicolas Rougemaille +8
Topological protection is an elegant way of warranting the integrity of quantum and nanosized systems. In magnetism one example is the Bloch-point, a peculiar object implying the l…
Reduction of magnetostatic interactions in self-organized arrays of nickel nanowires using atomic layer deposition
Sandrine Da Col, Michael Darques, Olivier Fruchart +1
Ordered arrays of magnetic nanowires are commonly synthesized by electrodeposition in nanoporous alumina templates. Due to their dense packing, strong magnetostatic interactions pr…
