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…
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…
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-…
