Charge dynamics in the Weyl semimetals NbIrTe and TaIrTe under pressure: Signatures of an electronic phase transition
M. Lamp, J. Ebad-Allah, A. Chmeruk +7
A high-pressure investigation of the Weyl semimetals NbIrTe and TaIrTe is presented, using infrared spectroscopy supplemented by density functional theory calculations. The…
Suppression of magnetism in CoSnS under external pressure
A. Chmeruk, D. Jones, R. Balducci +13
The ability to control the magnetic state provides a powerful means to tune the underlying band topology, enabling transitions between distinct electronic phases and the emergence…
Near room-temperature ferromagnetism from double-exchange in the van der Waals material CrGeTe: evidence from optical conductivity under pressure
Jihaan Ebad-Allah, Daniel Guterding, Meera Varma +4
The unexpected discovery of intrinsic ferromagnetism in layered van der Waals materials has sparked interest in both their fundamental properties and their potential for novel appl…
Optical anisotropy of the kagome magnet FeSn: Dominant role of excitations between kagome and Sn layers
J. Ebad-Allah, M. -C. Jiang, R. Borkenhagen +8
Antiferromagnetic FeSn is considered to be a close realization of the ideal two-dimensional (2D) kagome lattice, hosting Dirac cones, van Hove singularities, and flat bands, as it…
Signatures of van Hove singularities in the anisotropic in-plane optical conductivity of the topological semimetal NbSiTe
J. Ebad-Allah, A. A. Tsirlin, Y. L. Zhu +2
We present a temperature-dependent infrared spectroscopy study on the layered topological semimetal NbSiTe combined with density-functional theory (DFT) calculations of the…
In-plane and out-of-plane optical response of the nodal-line semimetals ZrGeS and ZrGeSe
J. Ebad-Allah, S. Rojewski, Y. L. Zhu +2
Polarization-dependent reflectivity measurements were carried out over a broad frequency range on single-crystalline ZrGeSe and ZrGeS compounds, which are closely related to the pr…
