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…

Ground state magnetic structure of Mn3Sn
Jeppe Jon Cederholm, Zhian Xu, Yanfeng Guo +11
We use spherical neutron polarimetry to determine the ground state magnetic structure of Mn3Sn. We find that Mn3Sn adopts an inverse triangular structure with spins parallel to <10…

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…
