Spin-phonon interactions and magnetoelectric coupling in CoO ( = Nb, Ta)
K. Park, J. Kim, S. Choi +10
In order to explore the consequences of spin-orbit coupling on spin-phonon interactions in a set of chemically-similar mixed metal oxides, we measured the infrared vibrational prop…
Large anomalous Hall effect and anisotropic magnetoresistance in intrinsic nanoscale spin-valve-type structure of an antiferromagnet
Dong Gun Oh, Jong Hyuk Kim, Mi Kyung Kim +6
A spin valve is a prototype of spin-based electronic devices found on ferromagnets, in which an antiferromagnet plays a supporting role. Recent findings in antiferromagnetic spintr…
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.…
