Multi-k magnetic structure and large anomalous Hall effect in candidate magnetic Weyl semimetal NdAlGe
C. Dhital, R. L. Dally, R. Ruvalcaba +15
The magnetic structure, magnetoresistance, and Hall effect of non-centrosymmetric magnetic semimetal NdAlGe are investigated revealing an unusual magnetic state and anomalous trans…
Anomalous magneto-elastic coupling in Au-doped BaFe2As2
S. -F. Wu, W. -L. Zhang, L. Li +6
We used polarization-resolved Raman scattering to study magneto-elastic coupling in Ba(FeAu)As crystals as a function of light Au-doping, materials for which…
The nature of spin excitations in the one-third magnetization plateau phase of BaCoSbO
Y. Kamiya, L. Ge, Tao Hong +10
Magnetization plateaus in quantum magnets---where bosonic quasiparticles crystallize into emergent spin superlattices---are spectacular yet simple examples of collective quantum ph…
Improving quantum-transition temperatures in BaFe2As2-based crystals by removing local-lattice strain & electronic-structure disorder
L. Li, Q. Zheng, Q. Zou +9
Quantum materials such as antiferromagnets or superconductors are complex in that chemical, electronic, and spin phenomena at atomic scales can manifest in their collective propert…
Destabilization of magnetic order in a dilute Kitaev spin liquid candidate
P. Lampen-Kelley, A. Banerjee, A. A. Aczel +6
The insulating honeycomb magnet -RuCl exhibits fractionalized excitiations that signal its proximity to a Kitaev quantum spin liquid (QSL) state, however, at , fragil…
Low-temperature crystal and magnetic structure of -RuCl3
H. B. Cao, A. Banerjee, J. -Q. Yan +6
Single crystals of the Kitaev spin-liquid candidate -RuCl have been studied to determine low-temperature bulk properties, structure and the magnetic ground state. Refinement…
Canted Magnetic Ground State of Quarter-Doped Manganites CaMnO ( = Y, Tb, Dy, Ho, and Er)
R. Sinclair, H. B. Cao, V. O. Garlea +6
Polycrystalline samples of the quarter-doped manganites CaMnO ( = Y, Tb, Dy, Ho, and Er) were studied by X-ray diffraction and AC/DC susceptibility measur…
Evolution of competing magnetic order in the Jeff=1/2 insulating state of Sr2Ir1-xRuxO4
S. Calder, J. W. Kim, G. -X. Cao +11
We investigate the magnetic properties of the series Sr2Ir1-xRuxO4 with neutron, resonant x-ray and magnetization measurements. The results indicate an evolution and coexistence of…
A magnetic topological semimetal Sr1-yMn1-zSb2 (y, z< 0.1)
J. Y. Liu, J. Hu, Q. Zhang +14
Weyl (WSMs) evolve from Dirac semimetals in the presence of broken time-reversal symmetry (TRS) or space-inversion symmetry. The WSM phases in TaAs-class materials and photonic cry…
Static and Dynamical Properties of the Spin-1/2 Equilateral Triangular-Lattice Antiferromagnet BaCoSbO
J. Ma, Y. Kamiya, Tao Hong +7
We present single-crystal neutron scattering measurements of the spin-1/2 equilateral triangular lattice antiferromagnet BaCoSbO. Besides confirming that the Co…
High antiferromagnetic transition temperature of a honeycomb compound SrRuO
W. Tian, C. Svoboda, M. Ochi +8
The high temperature magnetic order in SrRuO was studied by measuring magnetization and neutron powder diffraction with both polarized and unpolarized neutrons. SrRuO$_…
Strong competition between orbital-ordering and itinerancy in a frustrated spinel vanadate
J. Ma, J. H. Lee, S. E. Hahn +11
The crossover from localized- to itinerant-electron behavior is associated with many intriguing phenomena in condensed-matter physics. In this paper, we investigate the crossover f…
