Topological spin-texture transitions in van der Waals magnets revealed by X-ray Fourier transform holography
Sourav Chowdhury, Soumyaranjan Dash, Michael Schneider +14
Nontrivial topological spin-textures, such as skyrmions, merons, bimerons, and skyrmioniums, are envisioned as robust building blocks for future memory and logic devices. Controlla…
Linear dichroic soft X-ray microscopy of ferroelectric stripe domains in epitaxial KNaNbO
M. Schneider, T. A. Butcher, S. Wagner +19
Functional properties of ferroelectric thin films are governed by domains that can be engineered by epitaxial strain. Soft X-ray microscopy can image domain structures with element…
A fluctuation-free pathway for a topological magnetic phase transition
Riccardo Battistelli, Lukas Körber, Kai Litzius +27
Topological magnetic textures are particle-like spin configurations stabilized by competing interactions. Their formation is commonly attributed to fluctuation-driven, first-order…
Room temperature control of axial and basal antiferromagnetic anisotropies using strain
Jack Harrison, Junxiong Hu, Charles Godfrey +6
Antiferromagnetic materials are promising platforms for the development of ultra-fast spintronics and magnonics due to their robust magnetism, high-frequency relativistic dynamics,…
Nanoscale Domain Wall Dynamics in Micromagnetic Structures with Weak Perpendicular Anisotropy
Tim A. Butcher, Nicholas W. Phillips, Abraham L. Levitan +4
Time-resolved pump-probe soft X-ray ptychography and Scanning Transmission X-ray Microscopy (STXM) were employed to study the magnetic domain wall dynamics in microstructures of pe…
Imaging ferroelectric domains with soft X-ray ptychography at the oxygen K-edge
Tim A. Butcher, Nicholas W. Phillips, Chia-Chun Wei +7
The ferroelectric domain structure of a freestanding BiFeO film was visualized by ptychographic dichroic imaging with linearly polarized X-rays at the O K-edge around 530 eV. T…
