Chiral Magnon Mixing by Symmetry-Breaking in Collinear Ferrimagnets
Dhurba R. Jaishi, Tyler J. Slade, S. X. M. Riberolles +8
Magnons in ferromagnets possess spin angular momentum defined by right-handed precession of the moment around the magnetization direction. In antiferromagnets with no net magnetiza…
Emergent hidden order in ice: frustration and glassiness from slow hydrogen dynamics
Tianran Chen, D. Jonathan P. Morris, Isaac C. Ownby +9
Frustrated systems can host hidden order, in which weak interactions select correlated structure from a highly degenerate manifold. Water ice Ih is the canonical example of such a…
Gapped commensurate antiferromagnetic response in a strongly underdoped model cuprate superconductor
Zachary W. Anderson, Yang Tang, Vikram Nagarajan +13
It is a distinct possibility that spin fluctuations are the pairing interactions in a wide range of unconventional superconductors. In the case of the high-transition-temperature (…
Spin dynamics in itinerant antiferromagnet SrCrAs
Zhenhua Ning, Pinaki Das, Y. Lee +6
SrCrAs is an itinerant antiferromagnet in the same structural family as the SrFeAs high-temperature superconductors. We report our calculations of exchange-coupling…
Incipient nematicity from electron flat bands in a kagome metal
Nathan Drucker, Thanh Nguyen, Manasi Mandal +16
Engineering new quantum phases requires fine tuning of the electronic, orbital, spin, and lattice degrees of freedom. To this end, the kagome lattice with flat bands has garnered g…
Magnetic interactions and excitations in SrMnSb
Zhenhua Ning, Bing Li, Weilun Tang +7
The magnetic interactions in the antiferromagnetic (AFM) Dirac semimetal candidate SrMnSb are investigated using \textit{ab initio} linear response theory and inelastic neutron…
Spatial Correlation at the Boson Peak Frequency in Amorphous Materials
X. Y. Li, H. P. Zhang, S. Lan +5
The Boson peak (BP), an excess of vibrational density of states, is ubiquitous for amorphous materials and is believed to hold the key to understanding the dynamics of glass and gl…
Chiral and flat-band magnetic cluster excitations in a ferromagnetic kagome metal
S. X. M. Riberolles, Tyler J. Slade, Tianxiong Han +7
TbMn6Sn6 is a metallic ferrimagnet that displays signatures of band topology arising from a combination of uniaxial ferromagnetism and spin-orbit coupling within its Mn kagome laye…
Momentum and Energy Dependent Resolution Function of the ARCS Neutron Chopper Spectrometer at High Momentum Transfer: Comparing Simulation and Experimen
S. O. Diallo, J. Y. Y. Lin, D. L. Abernathy +1
Inelastic neutron scattering at high momentum transfers (i.e. Å) or DINS provides direct observation of the momentum distribution of light atoms, making it a powerful prob…
Comments on 'Phonon and magnetic structure in δ-plutonium from density-functional theory' by P. Söderlind et al
M. Janoschek, G. H. Lander, J. M. Lawrence +4
In their recent paper [Söderlind, P. et al., Sci. Rep. 5, 15958 (2015)], Söderlind et al. discuss two subjects from a theoretical point of view: the phonon spectra and the possible…
Light atom quantum oscillations in UC and US
Yuen Yiu, A. A. Aczel, G. E. Granroth +7
High energy vibrational scattering in the binary systems UC and US is measured using time-of-flight inelastic neutron scattering. A clear set of well-defined peaks equally separate…
Neutron Scattering Measurements of Spatially Anisotropic Magnetic Exchange Interactions in Semiconducting K0.85Fe1.54Se2 (TN=280 K)
Jun Zhao, Yao Shen, R. J. Birgeneau +7
We use neutron scattering to study the spin excitations associated with the stripe antiferromagnetic (AFM) order in semiconducting KFeSe (= K). We s…
Commensurate antiferromagnetic excitations as a signature of the pseudogap in the tetragonal high-Tc cuprate HgBaCuO
M. K. Chan, C. J. Dorow, L. Mangin-Thro +12
Antiferromagnetic correlations have been argued to be the cause of the d-wave superconductivity and the pseudogap phenomena exhibited by the cuprates. Although the antiferromagneti…
Glass-like phonon scattering from a spontaneous nanostructure in AgSbTe2
J. Ma, O. Delaire, A. F. May +11
Materials with very low thermal conductivity are of high interest for both thermoelectric and optical phase-change applications. Synthetic nanostructuring is most promising to supp…
