Imaging antiferromagnetic domains in LiCoPO via the optical magnetoelectric effect
B. Tóth, V. Kocsis, Y. Tokunaga +3
Antiferromagnetic (AFM) materials are considered as promising building blocks of novel data storage devices, still, detecting and manipulating AFM domains have remained challenging…
All-optical control of antiferromagnetic domains via an inverse optical magnetoelectric effect
Shingo Toyoda, Vilmos Kocsis, Yusuke Tokunaga +5
Antiferromagnets are a promising platform for next-generation spintronics due to their ultrafast spin dynamics and robustness to external fields. All-optical control of antiferroma…
Berry curvature generation detected by Nernst responses in ferroelectric Weyl semimetal
Cheng-Long Zhang, Tian Liang, M. S. Bahramy +6
The quest for nonmagnetic Weyl semimetals with high tunability of phase has remained a demanding challenge. As the symmetry breaking control parameter, the ferroelectric order can…
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 resonances of multiferroic TbFe(BO)
Dávid Szaller, Vilmos Kocsis, Sándor Bordács +6
Low-energy magnetic excitations of the easy-axis antiferromagnet TbFe(BO) are investigated by far-infrared absorption and reflection spectroscopy in high magnetic field…
Competing Exchange Interactions in the Multiferroic and Ferrimagnetic CaBaCoO
R. S. Fishman, S. Bordács, V. Kocsis +9
Competing exchange interactions can produce complex magnetic states together with spin-induced electric polarizations. With competing interactions on alternating triangular and kag…
Simultaneously Magnetic- and Electric-dipole Active Spin Excitations Govern the Static Magnetoelectric Effect in Multiferroic Materials
D. Szaller, S. Bordacs, V. Kocsis +3
We derive a sum rule to demonstrate that the static magnetoelectric (ME) effect is governed by optical transitions that are simultaneously excited via the electric and magnetic com…
Four-coloured Spin-wave Excitations in Multiferroic Materials
Istvan Kezsmarki, David Szaller, Sandor Bordacs +5
The optical magnetoelectric effect, which is an inherent attribute of the spin excitations in multiferroics, drastically changes their optical properties compared to conventional m…
