Strong magneto-optical effects in ACr2O4 A=Fe, Co spinel oxides generated by tetrahedrally coordinated transition metal ions
Vilmos Kocsis, Sándor Bordács, Joachim Deisenhofer +5
Magneto-optical effects have been investigated over the infrared{visible spectral range in ACr2O4 (A = Fe, Co) spinel oxides with non-collinear spin orders in their ground states.…
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…
Limits of Validity of Rashba Model in BiTeI: A High-field Magneto-optical Study
S. Bordacs, M. Orlita, M. Sikula +2
It was recently shown that BiTeI, a semiconductor with polar crystal structure, possesses a giant spin-splitting of electrons, which has been interpreted in terms of Rashba-type sp…
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…
