TL;DR: The first single-shot images of ferromagnetic, nanoscale spin order taken with femtosecond x-ray pulses are presented, opening new ways to combine ultrafast laser spectroscopy with sequential snapshot imaging on a single sample, generating a movie of excited state dynamics.
Journal ArticleDOI
Solvent additives and their effects on blend morphologies of bulk heterojunctions
Teddy Salim,Lydia Helena Wong,Björn Bräuer,Roopali Kukreja,Yong Lim Foo,Zhenan Bao,Yeng Ming Lam,Yeng Ming Lam +7 more
TL;DR: In this article, the additive-induced phase separation is related to the additive boiling point and the degree of interaction between the additive and fullerene, as evident from grazing incidence X-ray diffractometry (GIXRD) and scanning transmission Xray microscopy (STXM) data.
Journal ArticleDOI

TL;DR: The Verwey transition is investigated with pump-probe X-ray diffraction and optical reflectivity techniques, and how trimerons become mobile across the insulator-metal transition is found to be a two-step process.
Journal ArticleDOI
Nonuniform switching of the perpendicular magnetization in a spin-torque-driven magnetic nanopillar
David P. Bernstein,Björn Bräuer,Roopali Kukreja,Joachim Stöhr,Thomas Hauet,J. Cucchiara,Stéphane Mangin,Jordan A. Katine,Tolek Tyliszczak,Kang Wei Chou,Yves Acremann +10 more
TL;DR: In this article, the current-induced magnetization switching mechanism in nanopillars exhibiting strong perpendicular magnetic anisotropy (PMA) was studied using time-resolved scanning transmission x-ray microscopy (STXM) measurements.
Journal ArticleDOI
Deposition of thin films of a transition metal complex by spin coating
TL;DR: Spin coating is demonstrated to be a promising technique for depositing magnetic transition metal complexes as mentioned in this paper, which shows nano-crystalline formations with random orientations, indicating the preservation of the molecular structure upon the deposition process.
