THz spin-wave excitations in the transverse conical phase of BiFeO
B. Tóth, D. G. Farkas, K. Amelin +7
Although BiFeO is one of the most studied multiferroic materials, recent magnetization and neutron scattering studies have revealed a new magnetic phase in this compound - the…
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…
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…
Magnetic field control of cycloidal domains and electric polarization in multiferroic BiFeO
S. Bordács, D. G. Farkas, J. S. White +4
The magnetic field induced rearrangement of the cycloidal spin structure in ferroelectric mono-domain single crystals of the room-temperature multiferroic BiFeO is studied usin…
