Synthesizing skyrmion bound pairs in Fe-Gd thin films
James Lee,James Lee,Jordan Chess,S. A. Montoya,Xiaowen Shi,Nobumichi Tamura,S. K. Mishra,Peter Fischer,Peter Fischer,Benjamin J. McMorran,Sunil K. Sinha,Eric E. Fullerton,S. D. Kevan,S. D. Kevan,Sujoy Roy +14 more
TL;DR: In this article, it was shown that magnetic mirror symmetry planes present in the stripe phase, instead of chiral exchange, determine the internal skyrmion structure and the net achirality.

Soft x-ray ptychography studies of nanoscale magnetic and structural correlations in thin SmCo5 films
Peter Fischer,Xiaowen Shi,V. Neu,D. Elefant,James Lee,David A. Shapiro,Maryam Farmand,Tolek Tyliszczak,W. Shiu,Stefano Marchesini,Sujoy Roy,S. D. Kevan +11 more
TL;DR: In this article, high-resolution magnetic x-ray spectromicroscopy at xray photon energies near the cobalt L3 resonance was applied to probe an amorphous 50 nm thin SmCo5 film prepared by off-axis pulsed laser deposition onto an xray transparent Si3N4 membrane.

X-ray ptychography on low-dimensional hard-condensed matter materials
Xiaowen Shi,Nicolas Burdet,Bo Chen,Bo Chen,Gang Xiong,Robert Streubel,Ross Harder,Ian K. Robinson,Ian K. Robinson +8 more
TL;DR: In this paper, the authors discuss the current research examples of far-field diffraction-based X-ray ptychography on two-dimensional and three-dimensional semiconductors, ferroelectrics, and ferromagnets and their blooming future as a mainstream tool for materials sciences.
Propagation uniqueness in three-dimensional coherent diffractive imaging
TL;DR: In this paper, a two-step phasing procedure is introduced for reconstructing heavily-strained samples that balances the need to define both support and phase constraints, thus removing the nonuniqueness in simple cases but not for strong phase objects.
