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 Gd $_{2}$ SiO $_{5}$

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 $^{3 +}$ dopants t…

Magnetic structure of EuZn $_{2}$ Sb $_{2}$ 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 EuZn $_{2}$ Sb $_{2}$ , which has recently…

Nuclear quadrupole interaction and zero first-order Zeeman transitions of $^{167}$ Er $^{3 +}$ in CaWO $_{4}$

Lewin Marsh, Yikai Yang, Cesare Mattiroli +5

We report microwave spectroscopy of $^{167}$ Er $^{3 +}$ doped in CaWO $_{4}$ which reveals the hyperfine splitting of the erbium electronic ground state ( $Z_{1}$ , $J_{eff.}$ =15/2)…

Goldstone mode of the broken helix in U(1) magnet EuIn2As2

Alex Liebman-Pelaez, Samuel J. Garratt, Veronika Sunko +5

Goldstone modes acquire a frequency gap in the presence of perturbations that break the underlying continuous symmetry. Here, we study the response of a spin-based Goldstone mode t…

Magnetic structure of EuCd $_{2}$ Sb $_{2}$ single-crystal thin-film

Eliot Heinrich, Ayano Nakamura, Shinichi Nishihaya +5

We investigate the magnetic order in single crystalline EuCd $_{2}$ Sb $_{2}$ thin films using a combined theoretical and experimental approach. Resonant elastic x-ray scattering experime…

Spin dynamics and possible topological magnons in non-stoichiometric pyrochlore iridate Tb $_{2}$ Ir $_{2}$ O $_{7}$ 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 Tb $_{2 + x}$ Ir $_{2 - x}$ O $_{7 - y}$ ( $x ≃ 0.25$ ) that magnetical…
