Higher-order Weyl nodes driven by helical magnetic order in EuAgAs
Jian-Rui Soh, Ziming Zhu, Louis Withers +8
Magnetic topological semimetals provide a fertile ground for exploring how long-range magnetic order can alter electronic band structures and generate novel quasiparticles such as…
Elucidating magnetic structure with optical dopants: erbium-doped GdSiO
Luke S. Trainor, Masaya Hiraishi, J. -R. Soh +1
The narrowness of the optical transitions of rare-earth-ion dopants makes them highly sensitive probes of their environment. We measured the optical transitions Er dopants t…
Magnetic structure of EuZnSb single-crystal thin-film
Yu Wei Soh, Hsiang Lee, Eugen Weschke +4
Magnetic topological materials are a class of compounds which can host massless electrons controlled by the magnetic order. One such compound is EuZnSb, which has recently…
Spin dynamics and possible topological magnons in non-stoichiometric pyrochlore iridate TbIrO studied by RIXS
Q. Faure, A. Toschi, J. R. Soh +5
We report a resonant inelastic X-ray scattering study on a single crystal of a non-stoichiometric pyrochlore iridate TbIrO () that magnetical…
