Sign-tunable anisotropic magnetoresistance and electrically detectable dual magnetic phases in a helical antiferromagnet
Jong Hyuk Kim, Hyun Jun Shin, Mi Kyung Kim +6
The helimagnetic order describes a non-collinear spin texture of antiferromagnets, arising from competing exchange interactions. Although collinear antiferromagnets are elemental b…
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…
Evolution of electronic structure of Ru-doped single-crystal iridiates, SrIrRuO
Seokbae Lee, Yu-Seong Seo, Eilho Jung +7
We investigated Ru-doped single-crystal 5 iridiates, SrIrRuO, at three different doping concentrations ( 0.01, 0.07 and 0.10) using optical spectrosco…
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.…
Evidence for the Alternating Next-Nearest Neighbor model in the dynamic behavior of a frustrated antiferromagnet
Adra Carr, John Bowlan, 3 +12
X-ray photon correlation spectroscopy (XPCS) enables us to study dynamics of antiferromagnets. Using coherent soft X-ray diffraction, we resonantly probe Mn and Co Bragg peaks in t…
Strong magnetoelectric coupling in mixed ferrimagnetic-multiferroic phases of a double perovskite
M. K. Kim, J. Y. Moon, S. H. Oh +3
Exploring new magnetic materials is essential for finding advantageous functional properties such as magnetoresistance, magnetocaloric effect, spintronic functionality, and multife…
