Kondo quasiparticle dynamics observed by resonant inelastic x-ray scattering
M. C. Rahn, K. Kummer, A. Hariki +18
Effective models focused on pertinent low-energy degrees of freedom have substantially contributed to our qualitative understanding of quantum materials. An iconic example, the Kon…
Collinear antiferromagnetic order in URuSiP revealed by neutron diffraction
M. C. Rahn, A. Gallagher, F. Orlandi +5
The hidden order phase in URuSi is highly sensitive to electronic doping. A special interest in silicon-to-phosphorus substitution is due to the fact that it may allow one,…
Magnetically induced metal-insulator transition in Pb2CaOsO6
Henrik Jacobsen, Hai L. Feng, Andrew J. Princep +14
We report on the structural, magnetic, and electronic properties of two new double-perovskites synthesized under high pressure; Pb2CaOsO6 and Pb2ZnOsO6. Upon cooling below 80 K, Pb…
Colossal magnetoresistance in a nonsymmorphic antiferromagnetic insulator
P. F. S. Rosa, Yuanfeng Xu, S. K. Kushwaha +14
Here we investigate antiferromagnetic EuInSb, a nonsymmorphic Zintl phase. Our electrical transport data show that EuInSb is remarkably insulati…
Phonons, Q-dependent Kondo spin fluctuations, and 4/phonon resonance in YbAl
Andrew D. Christianson, Victor R. Fanelli, Lucas Lindsay +7
The intermediate valence (IV) compound YbAl exhibits nonintegral valence (Yb 4 (5d6s) where z = 2+n = 2.75) in a moderately heavy (m* = 20-30me) ground stat…
Selective probing of magnetic order on Tb and Ir sites in stuffed TbIrO using resonant X-ray scattering
C. Donnerer, M. C. Rahn, E. Schierle +7
We study the magnetic structure of the "stuffed" (Tb-rich) pyrochlore iridate TbIrO, using resonant elastic x-ray scattering (REXS). In order to disentangle…
Nematic state in CeAuSb
S. Seo, Xiaoyu Wang, S. M. Thomas +9
At ambient pressure and zero field, tetragonal CeAuSb hosts stripe antiferromagnetic order at K. Here we first show via bulk thermodynamic probes and x-ray diff…
Magnetically driven loss of centrosymmetry in metallic Pb2CoOsO6
A. J. Princep, H. L. Feng, Y. F. Guo +11
We report magnetic, transport, neutron diffraction, and muon spin rotation data showing that PbCoOsO, a newly synthesized metallic double-perovskite with a centrosymmetric…
An ideal Weyl semimetal induced by magnetic exchange
J. -R. Soh, F. de Juan, M. G. Vergniory +15
Weyl semimetals exhibit exceptional quantum electronic transport due to the presence of topologically-protected band crossings called Weyl nodes. The nodes come in pairs with oppos…
Evidence for ground state and defect-induced spin glass behaviour in the pyrochlore osmate YOsO
N. R. Davies, C. V. Topping, H. Jacobsen +14
We present AC and DC magnetometry, heat capacity, muon spin relaxation (SR) and resonant inelastic X-ray scattering (RIXS) studies of the pyrochlore osmate YOsO. We…
Coupling of magnetic order and charge transport in the candidate Dirac semimetal EuCdAs
M. C. Rahn, J. -R. Soh, S. Francoual +7
We use resonant elastic x-ray scattering to determine the evolution of magnetic order in EuCdAs below \,K, as a function of temperature and applied magnet…
All-in all-out magnetic order and propagating spin-waves in Sm2Ir2O7
C. Donnerer, M. C. Rahn, M. Moretti Sala +7
Using resonant magnetic x-ray scattering we address the unresolved nature of the magnetic groundstate and the low-energy effective Hamiltonian of SmIrO, a prototypical…
