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…
Néel-type Skyrmion Lattice with Confined Orientation in the Polar Magnetic Semiconductor GaVS
I. Kézsmárki, S. Bordács, P. Milde +11
Following the early prediction of the skyrmion lattice (SkL) - a periodic array of spin vortices - it has been observed recently in various magnetic crystals mostly with chiral str…
Two-Dimensional Valley Electrons and Excitons in Noncentrosymmetric 3R MoS
Ryosuke Akashi, Masayuki Ochi, Sándor Bordács +4
We find that the motion of the valley electrons -- electronic states close to the and points of the Brillouin zone -- is confined into two dimension when the l…
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…
Giant directional dichroism of terahertz light in resonance with magnetic excitations of the multiferroic oxide BaCoGeO
I. Kezsmarki, N. Kida, H. Murakawa +3
We propose that concurrently magnetic and ferroelectric, i.e. multiferroic, compounds endowed with electrically-active magnetic excitations (electromagnons) provide a key to produc…
Experimental band structure of the nearly half-metallic CuCrSe: An optical and magneto-optical study
S. Bordács, I. Kézsmárki, K. Ohgushi +1
Diagonal and off-diagonal optical conductivity spectra have been determined form the measured reflectivity and magneto-optical Kerr effect (MOKE) over a broad range of photon energ…
