Refining magnetic interactions from the magnetic field dependence of spin-wave excitations in magnetoelectric LiFePO
L. Peedu, V. Kocsis, D. Szaller +13
We investigated the spin excitations of magnetoelectric by THz absorption spectroscopy in magnetic fields up to 33T. By studying their selection rules, we fou…
Resolving structural changes and symmetry lowering in spinel FeCr2S4
Donald M. Evans, Ola G. Grendal, Lilian Prodan +7
The cubic spinel FeCr2S4 has been receiving immense research interest because of its emergent phases and the interplay of spin, orbital and lattice degrees of freedom. Despite the…
Mode splitting of spin waves in magnetic nanotubes with discrete symmetries
Lukas Körber, István Kézsmárki, Attila Kákay
We investigate how geometry influences spin dynamics in polygonal magnetic nanotubes. We find that lowering the rotational symmetry of nanotubes by decreasing the number of planar…
Coexistence of antiferromagnetism and ferrimagnetism in adjacent honeycomb layers
D. Szaller, L. Prodan, K. Geirhos +12
Antiferromagnetic and ferro/ferrimagnetic orders are typically exclusive in nature, thus, their co-existence in atomic-scale proximity is expected only in heterostructures. Breakin…
Confirming the trilinear form of the optical magnetoelectric effect in the polar honeycomb antiferromagnet CoMoO
S. Reschke, D. G. Farkas, A. Strinić +9
Magnetoelectric phenomena are intimately linked to relativistic effects and also require the material to break spatial inversion symmetry and time reversal invariance. Magnetoelect…
Selection rules and dynamic magnetoelectric effect of the spin waves in multiferroic BiFeO
D. G. Farkas, D. Szaller, I. Kézsmárki +9
We report the magnetic field dependence of the THz absorption and non-reciprocal directional dichroism spectra of BiFeO measured on the three principal crystal cuts for fields…
In-situ electric field control of THz non-reciprocal directional dichroism in the multiferroic BaCoGeO
J. Vít, J. Viirok, L. Peedu +11
Non-reciprocal directional dichroism, also called the optical-diode effect, is an appealing functional property inherent to the large class of non-centrosymmetric magnets. However,…
Squeezing Néel-type Magnetic Modulations by Enhanced Dzyaloshinskii-Moriya interaction of Electrons
Ádám Butykai, Korbinian Geirhos, Dávid Szaller +10
In polar magnets, such as GaVS, GaVSe and VOSeO, modulated magnetic phases namely the cycloidal and the Néel-type skyrmion lattice states were identified ov…
Directional dichroism in the paramagnetic state of multiferroics: a case study of infrared light absorption in Sr2CoSi2O7 at high temperatures
J. Viirok, U. Nagel, T. Rõõm +12
The coexisting magnetic and ferroelectric orders in multiferroic materials give rise to a handful of novel magnetoelectric phenomena, such as the absorption difference for the oppo…
