High-resolution neutron diffraction determination of noncollinear antiferromagnetic order in the honeycomb magnetoelectric FeNbO
Raktim Datta, Kapil Kumar, Dong Gun Oh +7
Magnetoelectric systems offer potential for device applications exploiting coupled states between electric and magnetic properties. Among magnetoelectric materials, \FNO has attrac…
Magnetic Control of Ferroelectric Polarization in a Self-formed Single Magnetoelectric Domain of Multiferroic Ba3NbFe3Si2O14
Nara Lee, Young Jai Choi, Sang-Wook Cheong
We have discovered strong magnetoelectric (ME) effects in the single chiral-helical magnetic state of single-crystalline langasite Ba3NbFe3Si2O14 that is crystallographically chira…
Coupling between magnon and ligand-field excitations in magnetoelectric Tb3Fe5O12 garnet
T. D. Kang, E. Standard, K. H. Ahn +7
The spectra of far-infrared transmission in Tb3Fe5O12 magnetoelectric single crystals have been studied in the range between 15 and 100 cm-1, in magnetic fields up to 10 T, and for…
Surface Reconstruction of Hexagonal Y-doped HoMnO3 and LuMnO3 studied using low-energy electron diffraction
R. Vasic, J. T. Sadowski, Y. J. Choi +5
We have investigated the (0001) surfaces of several hexagonal manganite perovskites by low-energy electron diffraction (LEED) in order to determine if the surface periodicity is di…
Magnetic excitations and optical transitions in the multiferroic spin-1/2 system LiCuO
D. Hüvonen, U. Nagel, T. Rõõm +4
Magnetic excitations in cycloidal magnet LiCuO are explored using THz absorption spectroscopy in magnetic fields up to 12 T. Below the spin ordering temperature we observe…
3:1 magnetization plateau and suppression of ferroelectric polarization in an Ising chain multiferroic
Y. J. Jo, Seongsu Lee, E. S. Choi +6
Ferroelectric Ising chain magnet CaCoMnO (0.96) was studied in magnetic fields up to 33 T. Magnetization and neutron scattering measurements reveal suc…
