Noncollinear magnetic order, in-plane anisotropy, and magnetoelectric coupling in a pyroelectric honeycomb antiferromagnet NiMoO
Poonam Yadav, Suheon Lee, G. L. Pascut +7
NiMoO is a pyroelectric honeycomb antiferromagnet exhibiting peculiar changes of its electric polarization at magnetic transitions. NiMoO stands…
Band-Mott mixing hybridizes the gap in FeMoO
K. Park, G. L. Pascut, G. Khanal +9
We combined optical spectroscopy and first principles electronic structure calculations to reveal the charge gap in the polar magnet FeMoO. Iron occupation on the octah…
Noncollinear antiferromagnetic order in the buckled honeycomb lattice of magnetoelectric Co4Ta2O9 determined by single-crystal neutron diffraction
Sungkyun Choi, Dong Gun Oh, Matthias J. Gutmann +8
Co4Ta2O9 exhibits a three-dimensional magnetic lattice based on the buckled honeycomb motif. It shows unusual magnetoelectric effects, including the sign change and non-linearity.…
Highly nonlinear magnetoelectric effect in antiferromagnetic Co4Ta2O9 single crystals
Nara Lee, Dong Gun Oh, Sungkyun Choi +10
Strongly correlated materials with multiple order parameters provide unique insights into the fundamental interactions in condensed matter systems and present opportunities for inn…
Spectroscopic and first principle DFT+eDMFT study of complex structural, electronic, and vibrational properties of MoO (=Fe, Mn) polar magnets
T. N. Stanislavchuk, G. L. Pascut, A. P. Litvinchuk +8
Optical spectroscopy, X-ray diffraction measurements, density functional theory (DFT) and density functional theory + embedded dynamical mean field theory (DFT+eDMFT) have been use…
Spin-Liquid-Like State in Pure and Mn-Doped TbInO3 with Nearly Triangular Lattice
M. G. Kim, B. Winn, S. Chi +8
Inelastic neutron scattering studies in single crystals of TbInO3 and TbIn0.95Mn0.05O3 with nearly-triangular antiferromagnetic lattice are reported. At low energies, a broad and a…
