Lattice-charge coupling in a trilayer nickelate with intertwined density wave order
Xun Jia, Yao Shen, Harrison LaBollita +16
Intertwined charge and spin correlations are ubiquitous in a wide range of transition metal oxides and are often perceived as intimately related to unconventional superconductivity…
In-plane anisotropy of charge density wave fluctuations in 1-TiSe
Xuefei Guo, Anshul Kogar, Jans Henke +17
We report measurements of anisotropic triple- charge density wave (CDW) fluctuations in the transition metal dichalcogenide 1-TiSe over a large volume of reciprocal space…
Effect of disorder on the strain-tuned charge density wave multicriticality in PdErTe
Anisha G. Singh, Matthew Krogstad, Maja D. Bachmann +9
We explore, through a combination of x-ray diffraction and elastoresistivity measurements, the effect of disorder on the strain-tuned charge density wave and associated multicritic…
Diffuse Scattering from Correlated Electron Systems
Raymond Osborn, Damjan Pelc, Matthew Krogstad +2
The role of inhomegeneity in determining the properties of correlated electron systems is poorly understood because of the dearth of structural probes of disorder at the nanoscale.…
Competition between metal bonding and strain in tetragonal VMO (M = Nb, Mo)
Jacob F. Phillips, Tyra C. Douglas, Matthew A. Davenport +6
Though the effects of metal dopants on the electrostructural transition of rutile VO have been studied for many decades, there is still no consensus explanation for the observe…
Absence of a bulk charge density wave signature in x-ray measurements of UTe
Caitlin S. Kengle, Dipanjan Chaudhuri, Xuefei Guo +12
The long-sought pair density wave (PDW) is an exotic phase of matter in which charge density wave (CDW) order is intertwined with the amplitude or phase of coexisting, superconduct…
Exploration of magnetoelastic deformations in spin-chain compound CuBr
Biaoyan Hu, Yingying Peng, Xiaoqiang Liu +7
We investigate a spin- antiferromagnet, CuBr, which has quasi-one-dimensional structural motifs. The system has previously been observed to exhibit unusual Raman m…
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…
Stacking disorder in -RuCl via x-ray three-dimensional difference pair distribution function analysis
J. Sears, Y. Shen, M. J. Krogstad +10
The van der Waals layered magnet -RuCl offers tantalizing prospects for the realization of Majorana quasiparticles. Efforts to understand this are, however, hampered by inco…
Spin and charge density waves in the quasi-one-dimensional KMn6Bi5
Jin-Ke Bao, Huibo Cao, Matthew J. Krogstad +9
AMn6Bi5 materials (A = Na, K, Rb and Cs) consisting of unique Mn-cluster chains emerge as a new family of superconductors with the suppression of their antiferromagnetic (AFM) orde…
Bragg glass signatures in PdErTe with X-ray diffraction Temperature Clustering (X-TEC)
Krishnanand Mallayya, Joshua Straquadine, Matthew Krogstad +6
The Bragg glass phase is a nearly perfect crystal with glassy features predicted to occur in vortex lattices and charge density wave systems in the presence of disorder. Detecting…
Order-Disorder Transitions in (CaSr)RhSn
Puspa Upreti, Matthew Krogstad, Charlotte Haley +6
The classification of structural phase transitions as displacive or order-disorder in character is usually based on spectroscopic data above the transition. We use single crystal x…
Competing Charge/Spin-Stripe and Correlated Metal Phases in Trilayer Nickelates (PrLa)NiO
Xinglong Chen, Hong Zheng, Daniel Phelan +6
Low-valent nickelates RNiO (R = rare earth) containing Ni (d) with a quasi-two-dimensional (quasi-2D) square planar coordination geometry possess…
Incommensurate magnetic orders and topological Hall effect in the square-net centrosymmetric EuGaAl system
Jaime M. Moya, Shiming Lei, Eleanor M. Clements +16
Neutron diffraction on the centrosymmetric square-net magnet EuGaAl reveals multiple incommensurate magnetic states (AFM1,2,3) in zero field. In applied field, a new magnet…
Harnessing Interpretable and Unsupervised Machine Learning to Address Big Data from Modern X-ray Diffraction
Jordan Venderley, Michael Matty, Krishnanand Mallayya +14
The information content of crystalline materials becomes astronomical when collective electronic behavior and their fluctuations are taken into account. In the past decade, improve…
Intertwined density waves in a metallic nickelate
J. Zhang, D. Phelan, A. S. Botana +10
Nickelates are a rich class of materials, ranging from insulating magnets to superconductors. But for stoichiometric materials, insulating behavior is the norm, as for most late tr…
Fragile 3D Order in VMoO
Matthew A. Davenport, Matthew J. Krogstad, Logan M. Whitt +6
The metal-to-insulator transition (MIT) in rutile VO has proven uniquely difficult to characterize because of the complex interplay between electron correlations and atomic str…
