Microscopic evidence for a Zhang-Rice triplet state in the van der Waals antiferromagnet, NiPS
Beom Hyun Kim, Youjin Lee, Junik Hwang +3
Quantum-entangled states underpin many emergent phenomena in quantum materials, yet their direct experimental identification remains a challenge. NiPS, a van der Waals antiferr…
Distinct Optical Excitation Mechanisms of a Coherent Magnon in a van der Waals Antiferromagnet
Clifford J. Allington, Carina A. Belvin, Urban F. P. Seifert +9
The control of antiferromagnets with ultrashort optical pulses has emerged as a prominent field of research. Tailored laser excitation can launch coherent spin waves at terahertz f…
Rapid suppression of quantum many-body magnetic exciton in doped van der Waals antiferromagnet (Ni,Cd)PS3
Junghyun Kim, Woongki Na, Jonghyeon Kim +7
The unique discovery of magnetic exciton in van der Waals antiferromagnet NiPS3 arises between two quantum many-body states of a Zhang-Rice singlet excited state and a Zhang-Rice t…
Coherent detection of hidden spin-lattice coupling in a van der Waals antiferromagnet
Emre Ergeçen, Batyr Ilyas, Junghyun Kim +7
Strong interactions between different degrees of freedom lead to exotic phases of matter with complex order parameters and emergent collective excitations. Conventional techniques,…
Field-tunable toroidal moment and anomalous Hall effect in noncollinear antiferromagnetic Weyl semimetal Co1/3TaS2
Pyeongjae Park, Yoon-Gu Kang, Junghyun Kim +4
Combining magnetism with band topology provides various novel phases that are otherwise impossible. Among several cases, noncollinear metallic antiferromagnets can reveal particula…
