Magnetic equivalent of electric superradiance: radiative damping in yttrium-iron-garnet films
L. Weymann, A. Shuvaev, A. Pimenov +2
A dense system of independent oscillators, connected only by their interaction with the same cavity excitation mode, will radiate coherently, which effect is termed superradiance.…
Band structure of a HgTe-based three-dimensional topological insulator
J. Gospodaric, V. Dziom, A. Shuvaev +5
From the analysis of the cyclotron resonance, we experimentally obtain the band structure of the three-dimensional topological insulator based on a HgTe thin film. Top gating was u…
Magnetic anisotropy and exchange paths for octa- and tetrahedrally coordinated Mn ions in the honeycomb multiferroic MnMoO
D. Szaller, K. Szász, S. Bordács +11
We investigated the static and dynamic magnetic properties of the polar ferrimagnet MnMoO in three magnetically ordered phases via magnetization, magnetic torque, and T…
Unusual magnetoelectric effect in paramagnetic rare-earth langasite
L. Weymann, L. Bergen, Th. Kain +13
Violation of time reversal and spatial inversion symmetries has profound consequences for elementary particles and cosmology. Spontaneous breaking of these symmetries at phase tran…
Sign change of polarization rotation under either time or space inversion in magnetoelectric YbAl3(BO3)4
A. M. Kuzmenko, V. Dziom, A. Shuvaev +4
Materials with optical activity can rotate the polarization plane of transmitted light. The most typical example is the natural optical activity, which has the symmetry property of…
High-frequency breakdown of the integer QHE in GaAs/AlGaAs heterojunctions
V. Dziom, A. Shuvaev, A. V. Shchepetilnikov +3
The integer quantum Hall effect is a well-studied phenomenon at frequencies below about 100 Hz. The plateaus in high-frequency Hall conductivity were experimentally proven to retai…
