Spectral signatures of a unique charge density wave in TaNiSe
Matthew D. Watson, Alex Louat, Cephise Cacho +4
Charge Density Waves (CDW) are commonly associated with the presence of near-Fermi level states which are separated from others, or "nested", by a wavector of . Here we…
Lattice dynamics and structural transition of the hyperhoneycomb iridate -LiIrO investigated by high-pressure Raman scattering
Sungkyun Choi, Heung-Sik Kim, Hun-Ho Kim +8
We report a polarized Raman scattering study of the lattice dynamics of -LiIrO under hydrostatic pressures up to 7.62 GPa. At ambient pressure, -LiIrO exhibit…
Inhomogeneous ferromagnetism mimics signatures of the topological Hall effect in SrRuO films
Gideok Kim, K. Son, Y. E. Suyolcu +11
Topological transport phenomena in magnetic materials are a major topic of current condensed matter research. One of the most widely studied phenomena is the ``topological Hall eff…
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.…
Tunable perpendicular exchange bias in oxide heterostructures
Gideok Kim, Yury Khaydukov, Martin Bluschke +9
The exchange bias effect is an essential component of magnetic memory and spintronic devices. Whereas recent research has shown that anisotropies perpendicular to the device plane…
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…
