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…
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…
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…
