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…
Magneto-optical detection of topological contributions to the anomalous Hall effect in a kagome ferromagnet
F. L. Schilberth, N. Unglert, L. Prodan +9
A single ferromagnetic kagome layer is predicted to realize a Chern insulator with quantized Hall conductance, which upon stacking can become a Weyl-semimetal with large anomalous…
Architecture of nanoscale ferroelectric domains in GaMo4S8
Erik Neuber, Peter Milde, Adam Butykai +10
Local-probe imaging of the ferroelectric domain structure and auxiliary bulk pyroelectric measurements were conducted at low temperatures with the aim to clarify the essential aspe…
Magnetic anisotropy and exchange paths for octa- and tetrahedrally coordinated Mn ions in the honeycomb multiferroic MnMoO
D. Szaller, K. Szász, S. Bordács +11
We investigated the static and dynamic magnetic properties of the polar ferrimagnet MnMoO in three magnetically ordered phases via magnetization, magnetic torque, and T…
Stability of Néel-type skyrmion lattice against oblique magnetic fields in GaVS and GaVSe
B. Gross, S. Philipp, K. Geirhos +5
The orientation of Néel-type skyrmions in the lacunar spinels GaVS and GaVSe is tied to the polar axes of their underlying crystal structure through the Dzyaloshins…
Macroscopic Manifestation of Domain-wall Magnetism and Magnetoelectric Effect in a Néel-type Skyrmion Host
K. Geirhos, B. Gross, B. G. Szigeti +12
We report a magnetic state in GaVSe which emerges exclusively in samples with mesoscale polar domains and not in polar mono-domain crystals. Its onset is accompanied with a…
Magnetoelectric memory function with optical readout
Vilmos Kocsis, Karlo Penc, Toomas Rõõm +8
The ultimate goal of multiferroic research is the development of new-generation non-volatile memory devices, the so-called magnetoelectric (ME) memories, where magnetic bits are co…
Characteristics of ferroelectric-ferroelastic domains in N{é}el-type skyrmion host GaVS
Ádám Butykai, Sándor Bordács, István Kézsmárki +6
GaVS is a multiferroic semiconductor hosting N{é}el-type magnetic skyrmions dressed with electric polarization. At T = 42K, the compound undergoes a structural phase tr…
Optical diode effect in the room-temperature multiferroic BiFeO$_3
I. Kezsmarki, U. Nagel, S. Bordacs +5
Multiferroics permit the magnetic control of the electric polarization and electric control of the magnetization. These static magnetoelectric (ME) effects are of enormous interest…
Multiferroicity and skyrmions carrying electric polarization in GaV4S8
E. Ruff, S. Widmann, P. Lunkenheimer +4
Skyrmions are whirl like topological spin objects with high potential for future magnetic data storage. It is a fundamental question, relevant for both basic research and applicati…
Evolution of the 2D antiferromagnetism with temperature and magnetic field in multiferroic BaCoGeO
V. Hutanu, A. P. Sazonov, M. Meven +11
We report on spherical neutron polarimetry and unpolarized neutron diffraction in zero magnetic field as well as flipping ratio and static magnetization measurements in high magnet…
Landau Level Spectroscopy of Dirac Electrons in a Polar Semiconductor with Giant Rashba Spin Splitting
Sándor Bordács, Joseph G. Checkelsky, Hiroshi Murakawa +2
Optical excitations of BiTeI with large Rashba spin splitting have been studied in an external magnetic field () applied parallel to the polar axis. A sequence of transitions be…
Symmetry Conditions for Non-reciprocal Light Propagation in Magnetic Crystals
David Szaller, Sandor Bordacs, Istvan Kezsmarki
Recent studies demonstrated the violation of reciprocity in optical processes in low-symmetry magnetic crystals. In these crystals the speed of light can be different for counter-p…
Chirality of Matter Shows Up via Spin Excitations
Sandor Bordacs, Istvan Kezsmarki, David Szaller +10
Right- and left-handed circularly polarized light interact differently with electronic charges in chiral materials. This asymmetry generates the natural circular dichroism and gyro…
Magnetic order induced crystal symmetry lowering in ACrO ferrimagnetic spinels
S. Bordacs, D. Varjas, I. Kezsmarki +6
We demonstrate that the onset of complex spin orders in ACrO spinels with magnetic ACo, Fe and Cu ions lowers the lattice symmetry. This is clearly indicated by the emer…
New type of ellipsometry in infrared spectroscopy: The double-reference method
I. Kezsmarki, S. Bordacs
