Optical magnetoelectric effect in the polar honeycomb antiferromagnet Fe2Mo3O8
K. V. Vasin, A. Strinic, F. Schilberth +7
The lack of both time-reversal and spatial inversion symmetry in polar magnets is a prerequisite for the occurrence of optical magnetoelectric effects such as nonreciprocal directi…
Quasimolecular =3/2 moments in the cluster Mott insulator GaTaSe
M. Magnaterra, J. Attig, L. Peterlini +8
Quasimolecular orbitals in cluster Mott insulators provide a route to tailor exchange interactions, which may yield novel quantum phases of matter. We demonstrate the cluster Mott…
Thermal decomposition of the Kitaev material -RuCl and its influence on low-temperature behavior
Franziska A. Breitner, Anton Jesche, Vladimir Tsurkan +1
We explore the effect of heat treatment in argon atmosphere under various temperatures up to C on single crystals of -RuCl by study of the mass loss, microprobe e…
Magnetization reversal through an antiferromagnetic state
Somnath Ghara, Evgenii Barts, Kirill Vasin +6
Magnetization reversal in ferro- and ferrimagnets is a well-known archetype of non-equilibrium processes, where the volume fractions of the oppositely magnetized domains vary and p…
Characterization of shell filling of interacting polarons in a quantum dot through their optical absorption
S. N. Klimin, V. M. Fomin, F. Brosens +1
The method for calculating the ground-state energy and the optical conductivity spectra is developed for a system of a finite number of interacting arbitrary-coupling polarons in a…
Theory of bound polarons in oxide compounds
J. T. Devreese, V. M. Fomin, E. P. Pokatilov +3
We present a multilateral theoretical study of bound polarons in oxide compounds MgO and α-Al_2O_3 (corundum). A continuum theory at arbitrary electron-phonon coupling is used for…
