Robust Long Range Magnetic Correlation across Anti-phase Domain Boundaries in SrCrReO
Bo Yuan, Subin Kim, Sae Hwan Chun +5
Anti-site disorder is one of the most important issues that arises in synthesis of double perovskite for spintronic applications. Although it is known that anti-site disorder leads…
Spin-Orbit Exciton in a Honeycomb Lattice Magnet CoTiO: Revealing Link Between Rare Earth and Transition Metal Magnetism
Bo Yuan, M. B. Stone, Guo-Jiun Shu +4
We carried out inelastic neutron scattering to study the spin-orbital (SO) exciton in a single crystal sample of CoTiO as a function of temperature. CoTiO is a honeycomb ma…
Dirac magnons in a honeycomb lattice quantum XY magnet CoTiO3
Bo Yuan, Ilia Khait, Guo-Jiun Shu +5
The discovery of massless Dirac electrons in graphene and topological Dirac-Weyl materials has prompted a broad search for bosonic analogues of such Dirac particles. Recent experim…
Neutron Scattering Study of Magnetic Anisotropy in a Tetragonal Antiferromagnet BiCuO
Bo Yuan, Nicholas P. Butch, Guangyong Xu +3
We present a comprehensive study of magnon excitations in the tetragonal easy-plane anti-ferromagnet BiCuO using inelastic neutron scattering and spin wave analyses. The na…
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…
Spin-orbit coupled systems in the "atomic" limit: rhenates, osmates, iridates
Arun Paramekanti, David J. Singh, Bo Yuan +4
Motivated by RIXS experiments on a wide range of complex heavy oxides, including rhenates, osmates, and iridates, we discuss the theory of RIXS for site-localized orbital…
