Tracking defects of Electronic Crystals by Coherent X-ray Diffraction
David Le Bolloc'h, E. Bellec, N. Kirova +1
In this article, we review different studies based on advanced x-ray diffraction techniques - especially coherent x-ray diffraction - that allowed us to reveal the behaviour of suc…
Imaging topological defects in a non-collinear antiferromagnet
Aurore Finco, Angela Haykal, Stéphane Fusil +9
We report on the formation of topological defects emerging from the cycloidal antiferromagnetic order at the surface of bulk BiFeO crystals. Combining reciprocal and real-space…
X-ray ptychographic topography, a new tool for strain imaging
Mariana Verezhak, Steven Van Petegem, Angel Rodriguez-Fernandez +7
Strain and defects in crystalline materials are responsible for the distinct mechanical, electric and magnetic properties of a desired material, making their study an essential tas…
The essential role of surface pinning in the dynamics of charge density waves submitted to external dc fields
E. Bellec, V. L. R. Jacques, J. Caillaux +1
A Charge Density Wave (CDW) submitted to an electric field displays a strong shear deformation because of pinning at the lateral surfaces of the sample. This CDW transverse pinning…
Current-induced nucleation and dynamics of skyrmions in a Co-based Heusler alloy
W. Akhtar, A. Hrabec, S. Chouaieb +9
We demonstrate room-temperature stabilization of dipolar magnetic skyrmions with diameters in the range of nm in a single ultrathin layer of the Heusler alloy CoFeAl (CFA…
Excitonic Emission in Organic-Inorganic Lead Iodide Perovskite Single Crystals
Hiba Diab, Gaëlle Trippé-Allard, Ferdinand Lédée +8
Hybrid perovskite thin films have demonstrated impressive performance for solar energy conversion and optoelectronic applications. However, further progress will benefit from a bet…
