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…
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…
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…
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…
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…
