Magnetic X-ray imaging using a single polarization and multimodal-ptychography
Marisel Di Pietro Martínez, Alexis Wartelle, Nicolas Mille +5
Polarized X-rays allow for imaging birefringent or dichroic properties of materials with nanometric resolution. To disentangle these properties from the electronic density, either…
Small-angle X-ray resonant magnetic scattering at the Co M and L edges observed with photoemission electron microscopy
Alexis Wartelle, Marisel Di Pietro Martínez, Olivier Fruchart +2
X-ray magnetic circular dichroism is an efficient contrast mechanism allowing for a direct sensitivity to magnetization. Combined with an imaging technique such as photoemission el…
Caustic spin wave beams in soft, thin films: properties and classification
Alexis Wartelle, Franz Vilsmeier, Takuya Taniguchi +1
In the context of wave propagation, caustics are usually defined as the envelope of a finite-extent wavefront; folds and cusps in a caustic result in enhanced wave amplitudes. Here…
Three-dimensional tomographic imaging of the magnetization vector field using Fourier transform holography
Marisel Di Pietro Martínez, Alexis Wartelle, Carlos Herrero Martínez +11
In recent years, interest in expanding from 2D to 3D systems has grown in the magnetism community, from exploring new geometries to broadening the knowledge on the magnetic texture…
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…
