Disorder and diffuse scattering in single-chirality (TaSe)I crystals
Jacob A. Christensen, Simon Bettler, Kejian Qu +11
The quasi-one-dimensional chiral compound (TaSe)I has been extensively studied as a prime example of a topological Weyl semimetal. Upon crossing its phase transition temper…
Zero-field magnetic structure and metamagnetic phase transitions of the cobalt chain compound LiCoCl
Zachary W. Riedel, Zhihao Jiang, Maxim Avdeev +2
Exploring the uncharacterized magnetic phases of Co chain compounds is critical for finding new low-dimensional magnets hosting quantized excitations. We map the unexplored…
Angstrom-Scale Imaging of Magnetization in Antiferromagnetic FeAs via 4D-STEM
Kayla X. Nguyen, Jeffrey Huang, Manohar H. Karigerasi +6
We demonstrate a combination of computational tools and experimental 4D-STEM methods to image the local magnetic moment in antiferromagnetic FeAs with 6 angstrom spatial resolu…
Observation of the massive Lee-Fukuyama phason in a charge density wave insulator
Soyeun Kim, Yinchuan Lv, Xiao-Qi Sun +10
The lowest-lying fundamental excitation of an incommensurate charge density wave (CDW) material is widely believed to be a massless phason -- a collective modulation of the phase o…
A new quasi-one-dimensional transition metal chalcogenide semiconductor (NbSeI)I
Kejian Qu, Zachary W. Riedel, Irián Sánchez-Ramírez +8
The discovery of new low-dimensional transition metal chalcogenides is contributing to the already prosperous family of these materials. In this study, needle-shaped single crystal…
Ultrafast x-ray scattering reveals composite amplitude collective mode in the Weyl charge density wave material (TaSe)I
Quynh L. Nguyen, Ryan A. Duncan, Gal Orenstein +27
We report ultrafast x-ray scattering experiments of the quasi-1D charge density wave (CDW) material (TaSe)I following photoexcitation with femtosecond infrared laser pulses…
