Phonon Dispersion of Mo-stabilized -U measured using Inelastic X-ray Scattering
Z. E. Brubaker, S. Ran, A. H. Said +7
We have measured the room-temperature phonon spectrum of Mo-stabilized U. The dispersion curves show unusual softening near the H point, q=[1/2,1/2,1/2], which may derive from…
Microscopic evidence for a chiral superconducting order parameter in the heavy fermion superconductor UTe2
Lin Jiao, Sean Howard, Sheng Ran +6
Spin-triplet superconductivity is a condensate of electron pairs with spin-1 and an odd-parity wavefunction. A particularly interesting manifestation of triplet pairing is a chiral…
Quasi-Two-Dimensional Magnon Identification in Antiferromagnetic FePS3 via Magneto-Raman Spectroscopy
Amber McCreary, Jeffrey R. Simpson, Thuc T. Mai +6
Recently it was discovered that van der Waals-bonded magnetic materials retain long range magnetic ordering down to a single layer, opening many avenues in fundamental physics and…
Quantum oscillations from networked topological interfaces in a Weyl semimetal
I-Lin Liu, Colin Heikes, Taner Yildirim +6
Layered transition metal chalcogenides are promising hosts of electronic Weyl nodes and topological superconductivity. MoTe is a striking example that harbors both noncentrosym…
Pressure Tuning of Collapse of Helimagnetic Structure in AuMn
I-Lin Liu, Maria J. Pascale, Juscelino B. Leao +4
We identify the phase boundary between spiral spin and ferromagnetic phases in AuMn at a critical pressure of 16.4 kbar, as determined by neutron diffraction, magnetization and…
Spectroscopic determination of the atomic f-electron symmetry underlying hidden order in URuSi
L. Andrew Wray, Jonathan Denlinger, Shih-Wen Huang +5
The low temperature hidden order state of URuSi has long been a subject of intense speculation, and is thought to represent an as yet undetermined many-body quantum state n…
Polarity-driven surface metallicity in SmB
Z. -H. Zhu, A. Nicolaou, G. Levy +7
By a combined angle-resolved photoemission spectroscopy and density functional theory study, we discover that the surface metallicity is polarity-driven in SmB. Two surface sta…
Spinodal Decomposition of Magnetic Ions in Eu-Codoped Ge/1-x/Cr/x/Te
A. Podgórni, L. Kilanski, W. Dobrowolski +9
We present the experimental evidence for the presence of spinodal decomposition of the magnetic ions in the Ge/1-x-y/Cr/x/Eu/y/Te samples with chemical composition varying in the r…
Layer-by-layer entangled spin-orbital texture of the topological surface state in Bi2Se3
Z. -H. Zhu, C. N. Veenstra, G. Levy +7
We study Bi2Se3 by polarization-dependent angle-resolved photoemission spectroscopy (ARPES) and density-functional theory slab calculations. We find that the surface state Dirac fe…
Intrinsic Electron-Phonon Resistivity in Bi2Se3 in the Topological Regime
Dohun Kim, Qiuzi Li, Paul Syers +4
We measure the temperature-dependent carrier density and resistivity of the topological surface state of thin exfoliated Bi2Se3 in the absence of bulk conduction. When the gate-tun…
Magnetic Interactions in Ge/1-x/Cr/x/Te Semimagnetic Semiconductors
L. Kilanski, A. Podgórni, W. Dobrowolski +10
We present the studies of magnetic properties of Ge/1-x/Cr/x/Te diluted magnetic semiconductor with changeable chemical composition 0.016 \leq x \leq 0.061. A spin-glass state (at…
High pressure transport properties of the topological insulator Bi2Se3
J. J. Hamlin, J. R. Jeffries, N. P. Butch +6
We report x-ray diffraction, electrical resistivity, and magnetoresistance measurements on Bi2Se3 under high pressure and low temperature conditions. Pressure induces profound chan…
Nitrogen Contamination in Elastic Neutron Scattering
Songxue Chi, Jeffrey W. Lynn, Ying Chen +6
Nitrogen gas accidentally sealed in a sample container produces various spurious effects in elastic neutron scattering measurements. These effects are systematically investigated a…
Non-collinear spin-density wave antiferromagnetism in FeAs
E. E. Rodriguez, C. Stock, K. Krycka +6
We present the magnetic structure of the itinerant monoarsenide, FeAs, with the B31 structure. Powder neutron diffraction confirms incommensurate modulated magnetism with wavevecto…
