Direct Observation and Analysis of Low-Energy Magnons with Raman Spectroscopy in Atomically Thin NiPS3
Woongki Na, Pyeongjae Park, Siwon Oh +6
Van der Waals (vdW) magnets have rapidly emerged as a fertile playground for novel fundamental physics and exciting applications. Despite the impressive developments over the past…
Composition dependence of bulk properties in the Co-intercalated transition-metal dichalcogenide CoTaS
Pyeongjae Park, Woonghee Cho, Chaebin Kim +5
Spontaneous Hall conductivity has recently been reported in the triangular lattice antiferromagnet CoTaS under a zero magnetic field. This phenomenon originates from th…
Quantum magnetism in the frustrated square lattice oxyhalides YbBi2IO4 and YbBi2ClO4
Pyeongjae Park, G. Sala, Th. Proffen +3
Square-lattice systems offer a direct route for realizing 2D quantum magnetism with frustration induced by competing interactions. In this work, the square-lattice materials YbBi2I…
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…
