Scanning through space and time: past, present, and future of time-resolved scanning transmission soft X-ray microscopy
Simone Finizio, Tim A. Butcher, Sebastian Wintz +2
Time-resolved microscopy with the pump-probe protocol is one of the most important techniques for the investigation of dynamical processes at the nanoscale, thanks to the possibili…
Ptychographic nanoscale imaging of the magnetoelectric coupling in freestanding BiFeO
Tim A. Butcher, Nicholas W. Phillips, Chun-Chien Chiu +14
Understanding the magnetic and ferroelectric ordering of magnetoelectric multiferroic materials at the nanoscale necessitates a versatile imaging method with high spatial resolutio…
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…
Single-photon counting pixel detector for soft X-rays
Filippo Baruffaldi, Anna Bergamaschi, Maurizio Boscardin +14
Soft X-ray experiments at synchrotron light sources are essential for a wide range of research fields. However, commercially available detectors for this energy range often cannot…
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…
Neutron imaging of liquid-liquid systems containing paramagnetic salt solutions
Tim A. Butcher, G. J. M. Formon, P. Dunne +4
The method of neutron imaging was adopted to map the concentration evolution of aqueous paramagnetic Gd(NO3)3 solutions. Magnetic manipulation of the paramagnetic liquid within a m…
