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…
Magnetoelectric spectroscopy of spin excitations in LiCoPO4
Vilmos Kocsis, Sándor Bordács, Yusuke Tokunaga +7
We have studied spin excitations in a single-domain crystal of antiferromagnetic LiCoPO4 by THz absorption spectroscopy. By analyzing the selection rules and comparing the strength…
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,…
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…
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…
