Room-temperature antiferromagnetic resonance in NaMnAs
Jan Dzian, StáÅa 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…
Spin-chiral electron-phonon coupling in metallic strontium titanate
N. Somun, L. RogiÄ, I. Khayr +12
Electron-phonon coupling (EPC) - the interaction between conduction electrons and quantized atomic vibrations - plays a central role in condensed matter physics and determines some…
Nonlinear Terahertz Electroluminescence from Dirac Landau Polaritons
B. Benhamou-Bui, C. Consejo, S. S. Krishtopenko +15
We report Dirac Landau polaritons observed by terahertz (THz) magnetoreflectivity spectroscopy, demonstrating strong coupling between cyclotron transitions of two-dimensional (2D)…
Dynamics of surface electrons in a topological insulator: cyclotron resonance at room temperature
I. Mohelsky, F. Le Mardele, J. Dzian +13
The ability to manipulate the surface states of topological insulators using electric or magnetic fields under ambient conditions is a key step toward their integration into future…
Magneto-Optical Study of Chiral Magnetic Modes in NiI: Direct Evidence for Kitaev Interactions
Kartik Panda, Chaebin Kim, Daniel Bazyliansky +13
Bond-dependent magnetic interactions, particularly those described by the Kitaev model, have emerged as a key pathway toward realizing unconventional magnetic states such as quantu…
Antiferromagnetic resonance in -MnTe
J. Dzian, P. KubaÅ¡ÄÃk, S. Tázlarů +20
Antiferromagnetic resonance in a bulk -MnTe crystal is investigated using both frequency-domain and time-domain THz spectroscopy techniques. At low temperatures, an excitation…
