Perpendicular magnetic anisotropy of cobalt films intercalated under graphene
N. Rougemaille, A. T. N'Diaye, J. Coraux +3
Magnetic properties of nanometer thick Co films intercalated at the graphene/Ir(111) interface are investigated using spin-polarized low-energy electron microscopy (SPLEEM) and Aug…
Non-universality of artificial frustrated spin systems
I. A. Chioar, N. Rougemaille, A. Grimm +6
Magnetic frustration effects in artificial kagome arrays of nanomagnets with out-of-plane magnetization are investigated using Magnetic Force Microscopy and Monte Carlo simulations…
Mechanism of current-assisted Bloch-point wall stabilization for ultra fast dynamics
A. De Riz, J. Hurst, M. Schöbitz +5
Two types of domain walls exist in magnetically soft cylindrical nanowires: the transverse-vortex wall (TVW) and the Bloch-point wall (BPW). The latter is expected to prevent the u…
Third type of domain wall in soft magnetic nanostrips
V. D. Nguyen, O. Fruchart, S. Pizzini +3
Magnetic domain walls (DWs) in nanostructures are low-dimensional objects that separate regions with uniform magnetisation. Since they can have different shapes and widths, DWs are…
Three-dimensional magnetic flux-closure patterns in mesoscopic Fe islands
R. Hertel, O. Fruchart, S. Cherifi +4
We have investigated three-dimensional magnetization structures in numerous mesoscopic Fe/Mo(110) islands by means of x-ray magnetic circular dichroism combined with photoemission…
Topological analysis and experimental control of transformations of domain walls in magnetic cylindrical nanowires
L. Ãlvaro-Gómez, J. Hurst, S. Hegde +9
Topology is a powerful tool for categorizing magnetization textures by defining a topological index in both two-dimensional (2D) systems, such as thin films or curved surfaces, and…
