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.…
The Magnetoelastic Distortion of Multiferroic BiFeO in the Canted Antiferromagnetic State
Toomas Rõõm, Johan Viirok, Laur Peedu +17
Using THz spectroscopy, we show that the spin-wave spectrum of multiferroic BiFeO in its high-field canted antiferromagnetic state is well described by a spin model that violat…
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…
Controlling of light with electromagnons
D. Szaller, A. Shuvaev, A. A. Mukhin +2
Magnetoelectric coupling in multiferroic materials opens new routes to control the propagation of light. The new effects arise due to dynamic magnetoelectric susceptibility that cr…
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…
Spin excitations of magnetoelectric LiNiPO in multiple magnetic phases
Laur Peedu, Vilmos Kocsis, Dávid Szaller +11
Spin excitations of magnetoelectric LiNiPO are studied by infrared absorption spectroscopy in the THz spectral range as a function of magnetic field through various commensurat…
