Journal ArticleDOI
Vortex Core-Driven Magnetization Dynamics
Sug-Bong Choe,Yves Acremann,Andreas Scholl,Andreas Bauer,Andreas Bauer,Andreas Bauer,Andrew Doran,Joachim Stöhr,Howard A. Padmore +8 more
TL;DR: Time-resolved x-ray imaging shows that the magnetization dynamics of a micron-sized pattern containing a ferromagnetic vortex is determined by its handedness, or chirality, which plays an important role in the dynamics of microscopic magnets.
Journal ArticleDOI
A SAXS/WAXS/GISAXS Beamline with Multilayer Monochromator
Alexander Hexemer,Wim Bras,James Glossinger,Eric Schaible,Eliot Gann,Richard A. Kirian,Alastair A. MacDowell,Matthew Church,Bruce Rude,Howard A. Padmore +9 more
TL;DR: In this article, the authors discuss the construction of a new SAXS/WAXS beamline at the Advanced Light Source at Lawrence Berkeley Laboratory, which is equipped with a multilayer monochromator in order to obtain a high X-ray flux.
Journal ArticleDOI
Soft x-ray scattering facility at the Advanced Light Source with real-time data processing and analysis.
Eliot Gann,Anthony Young,Brian Collins,Hongping Yan,J. Nasiatka,Howard A. Padmore,Harald Ade,Alexander Hexemer,Cheng Wang +8 more
TL;DR: Of special interest is the development of a higher harmonic rejection system that improves the spectral purity of the x-ray beam.
Journal ArticleDOI
Direct observation of the alignment of ferromagnetic spins by antiferromagnetic spins
F. Nolting,Andreas Scholl,Joachim Stöhr,Jin Won Seo,Jean Fompeyrine,Heinz Siegwart,Jean-Pierre Locquet,Simone Anders,Jan Lüning,Eric E. Fullerton,Michael F. Toney,M. R. Scheinfein,Howard A. Padmore +12 more
TL;DR: P polarization-dependent X-ray magnetic dichroism spectro-microscopy is presented that reveals the micromagnetic structure on both sides of a ferromagnetic–antiferromagnetic interface, implying that the alignment of the ferrom magnetic spins is determined, domain by domain, by the spin directions in the underlying antiferromagnet layer.
Journal ArticleDOI
Chemical composition mapping with nanometre resolution by soft X-ray microscopy
David A. Shapiro,Young-Sang Yu,Tolek Tyliszczak,Jordi Cabana,Jordi Cabana,R. S. Celestre,Weilun Chao,Konstantin Kaznatcheev,A. L. David Kilcoyne,Filipe R. N. C. Maia,Stefano Marchesini,Y. Shirley Meng,Tony Warwick,Lee Lisheng Yang,Howard A. Padmore +14 more
TL;DR: In this article, a soft X-ray ptychography approach was used to image 5-nm-sized objects, and chemical component distributions in the delithiation of LiFePO4 nanoplates linked structural defects to chemical phase propagation.
