Magnetic excitations in double perovskite iridates LaIrO ( = Co, Ni, and Zn) mediated by 3-5 hybridization
Wentao Jin, Sae Hwan Chun, Jungho Kim +6
By performing resonant inelastic x-ray scattering (RIXS) measurements at the Ir edge, we have investigated the low-energy elementary excitations in a seri…
Neutron Scattering Investigation of Rhenium Orbital Ordering in Double Perovskite CaFeReO
Bo Yuan, J. P. Clancy, J. A. Sears +9
We have carried out inelastic neutron scattering experiments to study magnetic excitations in ordered double perovskite CaFeReO. We found a well-defined magnon mode with a…
Local structural distortion induced by antiferromagnetic ordering in BiFeO studied using neutron total scattering analysis
I. -K. Jeong, N. Hur
To unravel the origin of the dielectric anomaly at the antiferromagnetic ordering of magnetoelectric BiFeO we performed neutron powder diffraction measurements across t…
Probing ultrafast spin dynamics in the antiferromagnetic multiferroic HoMnO through a magnon resonance
P. Bowlan, S. A. Trugman, J. Bowlan +5
We demonstrate a new approach for directly measuring the ultrafast energy transfer between elec- trons and magnons, enabling us to track spin dynamics in an antiferromagnet (AFM).…
Quadrupolar Singlet Ground State of Praseodymium in a Modulated Pyrochlore
J. van Duijn, K. H. Kim, N. Hur +12
The complex structure and magnetism of PrBiRuO was investigated by neutron scattering and EXAFS. Pr has an approximate doublet ground-state and the first excite…
Spin-Chiral Bulk Fermi Surfaces of BiTeI Proven by Quantum Oscillations
Joonbum Park, E. Kampert, Kyung-Hwan Jin +10
We present the Fermi-surface map of the spin-chiral bulk states for the non-centrosymmetric semiconductor BiTeI using de Haas-van Alphen and Shubnikov-de Haas oscillations. We iden…
Chiral orbital-angular-momentum in the surface states of Bi2Se3
Seung Ryong Park, Jinhee Han, Chul Kim +11
Locking of the spin of a quasi-particle to its momentum in split bands of on the surfaces of metals and topological insulators (TIs) is understood in terms of Rashba effect where a…
Epitaxial growth of multiferroic Pb(Zr0.57Ti0.43)O3-Pb(Fe2/3W1/3)O3 solid-solution thin films and their magnetoelectric effects
D. Lee, Y. -A. Park, S. M. Yang +5
We report on epitaxial growth of single-phase [Pb(Zr0.57Ti0.43)O3]0.8[Pb(Fe2/3W1/3)O3]0.2 (PZT-PFW) solid-solution thin films using pulsed laser deposition. X-ray diffraction measu…
Quasi-particle scattering and protected nature of topological states in a parent topological insulator BiSe
S. R. Park, W. S. Jung, Chul Kim +5
We report on angle resolved photoemission spectroscopic studies on a parent topological insulator (TI), BiSe. The line width of the spectral function (inverse of the quasi-…
