Non-magnetic ion site disorder effects on the quantum magnetism of a spin-1/2 equilateral triangular lattice antiferromagnet
Q. Huang, R. Rawl, W. W. Xie +12
With the motivation to study how non-magnetic ion site disorder affects the quantum magnetism of Ba3CoSb2O9, a spin-1/2 equilateral triangular lattice antiferromagnet, we performed…
Decoupling of Lattice and Orbital Degrees of Freedom in an Iron-Pnictide Superconductor
Christian E. Matt, O. Ivashko, M. Horio +16
The interplay of structural and electronic phases in iron-based superconductors is a central theme in the search for the superconducting pairing mechanism. While electronic nematic…
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…
Engineering the structural and electronic phases of MoTe2 through W substitution
D. Rhodes, D. A. Chenet, B. E. Janicek +30
MoTe is an exfoliable transition metal dichalcogenide (TMD) which crystallizes in three symmetries, the semiconducting trigonal-prismatic phase, the semimetallic $1T^{\pri…
Orbital-differentiated coherence-incoherence crossover identified by photoemission spectroscopy in LiFeAs
H. Miao, Z. P. Yin, S. F. Wu +12
In the iron-based superconductors (FeSCs), orbital differentiation is an important phenomenon, whereby correlations stronger on the dxy orbital than on the dxz/yz orbital yield qua…
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…
The anomaly Cu doping effects on LiFeAs superconductors
L. Y. Xing, H. Miao, X. C. Wang +5
The Cu substitution effect on the superconductivity of LiFeAs has been studied in comparison with Co/Ni substitution. It is found that the shrinking rate of the lattice parameter c…
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…
Observation of anomalous temperature dependence of spectrum on small Fermi surfaces in a BiS2-based superconductor
L. K. Zeng, X. B. Wang, J. Ma +7
We performed an angle-resolved photoemission spectroscopy study of the BiS2-based superconductor Nd(O,F)BiS2. Two small electron-like Fermi surfaces around X (pi, 0) are observed,…
Role of Magnetic Exchange Energy on Charge Ordering in RSFO (R=La, Pr, and Nd)
J. Ma, J. -Q. Yan, S. O. Diallo +6
Inelastic neutron scattering is applied to study the role of magnetism in stabilizing the charge ordered state in \emph{R}SrFeO (\emph{R}SFO) (\emph{R} = La,…
Stabilization of charge ordering in La_(1/3)Sr_(2/3)FeO_(3-d) by magnetic exchange
R. J. McQueeney, J. Ma, S. Chang +3
The magnetic exchange energies in charge ordered La_(1/3)Sr_(2/3)FeO_(3-d) (LSFO) and its parent compound LaFeO_(3) (LFO) have been determined by inelastic neutron scattering. In L…
