Characterization of Chromium Impurities in -GaO
Mark E. Turiansky, Sai Mu, Lukas Razinkovas +8
Chromium is a common transition-metal impurity that is easily incorporated during crystal growth. It is perhaps best known for giving rise to the 694.3 nm (1.786 eV) emission in Cr…
Phase-Separated Charge Order and Twinning Across Length Scales in CsVSb
Jayden Plumb, Andrea Capa Salinas, Krishnanand Mallayya +9
We present X-ray scattering studies resolving structural twinning and phase separation in the charge density wave (CDW) state of the kagome superconductor CsVSb. The three-…
Frustrated Ising charge correlations in the kagome metal ScVSn
S. J. Gomez Alvarado, G. Pokharel, B. R. Ortiz +4
Here we resolve the real-space nature of the high-temperature, short-range charge correlations in the kagome metal ScVSn. Diffuse scattering appears along a frustrated wave…
Advances in high-pressure laser floating zone growth: the Laser Optical Kristallmacher II
Steven J. Gomez Alvarado, Eli Zoghlin, Azzedin Jackson +9
The optical floating zone crystal growth technique is a well-established method for obtaining large, high-purity single crystals. While the floating zone method has been constantly…
Revisiting spin ice physics in the ferromagnetic Ising pyrochlore PrSnO
Brenden R. Ortiz, Paul M. Sarte, Ganesh Pokharel +12
Pyrochlore materials are characterized by their hallmark network of corner-sharing rare-earth tetrahedra, which can produce a wide array of complex magnetic ground states. Ferromag…
Fermi surface of magnetic kagome compound GdV6Sn6 investigated using de Haas van Alphen Oscillations
C. Dhital, G. Pokharel, B. Wilson +6
The shape of the Fermi surface, and the cyclotron effective mass of the kagome magnet GdV6Sn6 charge carriers are investigated using de Haas van Alphen (dHvA) oscillations measurem…
Realizing Kagome Band Structure in Two-Dimensional Kagome Surface States of (=Gd,Ho)
Shuting Peng, Yulei Han, Ganesh Pokharel +14
We report angle resolved photoemission experiments on a newly discovered family of kagome metals (=Gd, Ho). Intrinsic bulk states and surface states of the vanadi…
Spin dynamics in the skyrmion-host lacunar spinel GaV4S8
G. Pokharel, H. Suriya Arachchige, S. Gao +10
In the lacunar spinel GaV4S8, the interplay of spin, charge, and orbital degrees of freedom produces a rich phase diagram that includes an unusual Neel-type skyrmion phase composed…
Hierarchical excitations from correlated spin tetrahedra on the breathing pyrochlore lattice
Shang Gao, Andrew F. May, Mao-Hua Du +10
The hierarchy of the coupling strengths in a physical system often engenders an effective model at low energies where the decoupled high-energy modes are integrated out. Here, usin…
Complex magnetic phases in polar tetragonal intermetallic NdCoGe
Binod K. Rai, Ganesh Pokharel, Hasitha Suriya Arachchige +8
Polar materials can host a variety of topologically significant magnetic phases, which often emerge from a modulated magnetic ground state. Relatively few noncentrosymmetric tetrag…
Cluster Frustration in the Breathing Pyrochlore Magnet LiGaCr4S8
Ganesh Pokharel, Hasitha Suriya Arachchige, Travis J. Williams +11
We present a comprehensive neutron scattering study of the breathing pyrochlore magnet LiGaCr4S8. We observe an unconventional magnetic excitation spectrum with a separation of hig…
