Fresnel diffraction imaging of surface nanostructure using coherent resonant X-ray scattering
L. Burgard, C. Neupane, A. Balodhi +9
We investigated surface nanostructures on an antiferromagnet MnBiTe using a novel imaging technique, direct (real)-space and real time coherent X-ray imaging (direct-CXI).…
X-ray Fractional Orbital Angular Momentum from Coherent Magnetic Scattering
P. D. Montgomery, J. S. Woods, M. R. McCarter +10
Artificial spin ice (ASI) based on a square lattice with a topological defect are known to generate orbital angular momentum (OAM) in diffracted X-ray beams. A previous investigati…
Excitations across the equilibrium and photoinduced `hidden' states of magnetoresistive manganites
Shiyu Fan, Feng Jin, Taehun Kim +16
"Hidden" phases, generated using ultrafast laser pulses (few hundred femtoseconds), with properties distinct from thermodynamic equilibrium, are appealing for technologies because…
Dynamics and formation of antiferromagnetic textures in MnBiTe single crystal
M. G. Kim, S. Boney, L. Burgard +2
We report coherent X-ray imaging of antiferromagnetic (AFM) domains and domain walls in MnBiTe, an intrinsic AFM topological insulator. This technique enables direct visual…
Evidence of electronic states driving current-induced insulator-to-metal transition
V. K. Bhartiya, R. Hartmann, F. Forte +16
On demand current-driven insulator-to-metal transition (IMT) is pivotal for the next generation of energy-efficient and scalable microelectronics. IMT is a key phenomenon observed…
Magnetic excitations and absence of charge order in the van der Waals ferromagnet FeGeTe
V. K. Bhartiya, T. Kim, J. Li +12
Understanding the ground state of van der Waals (vdW) magnets is crucial for designing devices leveraging these platforms. Here, we investigate the magnetic excitations and charge…
Capping effects on spin and charge excitations in parent and superconducting Nd1-xSrxNiO2
S. Fan, H. LaBollita, Q. Gao +19
Superconductivity in infinite layer nickelates Nd1-xSrxNiO2 has so far been achieved only in thin films raising questions on the role of substrates and interfaces. Given the challe…
Spontaneous Magnetic Superdomain Wall Fluctuations in an Artificial Antiferromagnet
X. M. Chen, B. Farmer, J. S. Woods +8
Collective dynamics often play an important role in determining the stability of ground states for both naturally occurring materials and metamaterials. We studied the temperature…
High-energy spin and charge excitations in electron-doped copper oxide superconductors
K. Ishii, M. Fujita, T. Sasaki +15
The evolution of electronic (spin and charge) excitations upon carrier doping is an extremely important issue in superconducting layered cuprates and the knowledge of its asymmetry…
Direct observation of bulk charge modulations in optimally-doped BiPbSrCaCuO
M. Hashimoto, G. Ghiringhelli, W. -S. Lee +12
Bulk charge density modulations, recently observed in high critical-temperature () cuprate superconductors, coexist with the so-called pseudogap and compete with supe…
Long-range incommensurate charge fluctuations in (Y,Nd)Ba2Cu3O(6+x)
G. Ghiringhelli, M. Le Tacon, M. Minola +17
There are increasing indications that superconductivity competes with other orders in cuprate superconductors, but obtaining direct evidence with bulk-sensitive probes is challengi…
