Room-temperature antiferromagnetic resonance in NaMnAs
Jan Dzian, Stáňa Tázlarů, Ivan Mohelský +16
We report on antiferromagnetic resonance experiments in bulk tetragonal NaMnAs -- a room-temperature antiferromagnetic semiconductor. Our results corroborate previous ab initio stu…
Magneto-optical response of magnetic semiconductors EuCd2X2 (X= P, As, Sb)
S. Nasrallah, D. Santos-Cottin, F. Le Mardele +16
In this study, we identify EuCd2X2 (for X = P, As, Sb) as a series of magnetic semiconductors. We examine how the band gap of the series responds to X changing from phosphorus (P),…
Electronic band structure of Sb2Te3
I. Mohelsky, J. Wyzula, F. Le Mardele +11
Here we report on Landau level spectroscopy of an epitaxially grown thin film of the topological insulator Sb2Te3, complemented by ellipsometry and magneto-transport measurements.…
Evidence of 3D Dirac conical bands in TlBiSSe by optical and magneto-optical spectroscopy
F. Le Mardelé, J. Wyzula, I. Mohelsky +15
TlBiSSe is a rare realization of a 3D semimetal with a conically dispersing band that has an optical response which is well isolated from other contributions in a broad range of ph…
EuCdAs: a magnetic semiconductor
D. Santos-Cottin, I. Mohelský, J. Wyzula +18
EuCdAs is now widely accepted as a topological semimetal in which a Weyl phase is induced by an external magnetic field. We challenge this view through firm experimental ev…
Optical conductivity signatures of open Dirac nodal lines
D. Santos-Cottin, M. Casula, L. de' Medici +7
We investigate the optical conductivity and far-infrared magneto-optical response of BaNiS, a simple square-lattice semimetal characterized by Dirac nodal lines that disperse e…
