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…
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…
Generation of Weyl points and a nodal line by magnetization reorientation in CoSnS
F. Schilberth, M. -C. Jiang, F. Le Mardelé +11
Topological magnets exhibit fascinating properties like topologically protected surface states or anomalous transport phenomena. While these properties can be significantly altered…
Large magnetoreflectance and optical anisotropy due to flat bands in the frustrated kagome magnet HoAgGe
F. Schilberth, L. DeFreitas, K. Zhao +7
We report peculiar optical properties of the frustrated itinerant magnet HoAgGe, which exhibits multiple magnetically ordered states obeying the kagome spin-ice rule. The optical c…
Low-energy excitations in multiple modulation-doped CdTe/(CdMg)Te quantum wells
D. Yavorskiy, F. Le Mardelé, I. Mohelsky +6
Low energy excitations of a two-dimensional electron gas (2DEG) in modulation-doped multiple (ten) quantum wells (QWs) was studied using far-infrared magneto-transmission technique…
Tuning THz magnons in a mixed van-der-Waals antiferromagnet
F. Le Mardele, I. Mohelsky, D. Jana +9
Alloying stands out as a pivotal technological method employed across various compounds, be they metallic, magnetic, or semiconducting, serving to fine-tune their properties to mee…
