Spin-phonon interactions and magnetoelectric coupling in CoO ( = Nb, Ta)
K. Park, J. Kim, S. Choi +10
In order to explore the consequences of spin-orbit coupling on spin-phonon interactions in a set of chemically-similar mixed metal oxides, we measured the infrared vibrational prop…
Anisotropic Correlated Electronic Structure of Colossal Thermopower Marcasite FeSb
A. Chikina, J. -Z. Ma, W. H. Brito +9
Iron antimonide (FeSb) is a mysterious material with peculiar colossal thermopower of about mV/K at 10 K. However, a unified microscopic description of this phenomenon is…
Decoupled Pairing Amplitude and Electronic Coherence in Iron-Based Superconductors
H. Miao, W. H. Brito, Z. P. Yin +12
Here we use angle-resolved photoemission spectroscopy to study superconductivity that emerges in two extreme cases, from a Fermi liquid phase (LiFeAs) and an incoherent bad-metal p…
Orbital-dependent correlations in PuCoGa
W. H. Brito, S. Choi, Y. X. Yao +1
We investigate the normal state of the superconducting compound PuCoGa using the combination of density functional theory (DFT) and dynamical mean field theory (DMFT), with the…
Magnetic orders, excitations, and phase transitions in Fe_1+yTe
G. Chen, S. Choi, L. Radzihovsky
We study the magnetic properties of Fe_1+y Te, a parent compound of the iron-based high-temperature superconductors. Motivated by recent neutron scattering experiments, we show tha…
Spin waves and revised crystal structure of honeycomb iridate Na2IrO3
S. K. Choi, R. Coldea, A. N. Kolmogorov +11
We report inelastic neutron scattering measurements on Na2IrO3, a candidate for the Kitaev spin model on the honeycomb lattice. We observe spin-wave excitations below 5 meV with a…
