Magnetic Field Control of the Néel Vector and Magnon Visibility in Altermagnetic MnTe
Tobias Weber, Niclas Heinsdorf, Shane Smolenski +11
Altermagnetic order gives rise to momentum-dependent spin splitting of electronic and magnonic excitations even in the absence of a net magnetization. Here, we investigate the magn…
Lattice Dynamics of LiFeAs studied by Inelastic Neutron Scattering and Density Functional Theory calculations
Akshay Tewari, Navid Qureshi, Rolf Heid +6
We investigated the lattice dynamics of the unconventional superconductor LiFeAs using inelastic neutron scattering experiments and density-functional theory (DFT) calculations. By…
Magnetic excitations in the Kitaev material NaIrO studied by neutron scattering
Alexandre Bertin, Hengdi Zhao, Gang Cao +4
Inelastic neutron scattering experiments with a large set of comounted NaIrO crystals reveal the low-energy magnon dispersion in this candidate material for Kitaev physics.…
Lattice dynamics of hexagonal ZnMgS
Abdelmahjid Elmahjoubi, Mala Rao, Alexandre Ivanov +10
Inelastic neutron scattering measurements on the hexagonal Zn67Mg33S semiconductor alloy reveal a bimodal pattern of the optical modes across the Brillouin zone, confirmed by first…
