Probing intrinsic magnetic phases in low-dimensional nearly twin-free NiPS single crystals
Yeochan An, Heejun Yang, Sung Jin Park +6
We report the intrinsic thermal and magnetic properties of the low-dimensional van der Waals (vdW) antiferromagnet NiPS and explore its emergent magnetic phases by controlling…
Interfacial chirality-induced magnetic-field-free switching with high energy efficiency in all-vdW heterostructures
Kai-Xuan Zhang, Suik Cheon, Seungbok Lee +12
Chirality, a central concept across many scientific disciplines, continues to inspire the discovery of novel physical phenomena. In condensed matter physics, structural chirality -…
Composition-dependent bulk properties of intercalated transition metal dichalcogenides
Woonghee Cho, Kiwan Nam, Yeochan An +4
We report a systematic study of the composition-dependent bulk properties in single crystals across a series of precisely controlled cobalt compositions wi…
Current Switching of Topological Spin Chirality in the van der Waals Antiferromagnet Co1/3TaS2
Kai-Xuan Zhang, Seungbok Lee, Woonghee Cho +1
Magnetic topology is central to modern quantum magnet, where spin chirality governs exotic spin winding, real-space Berry phase, and topological Hall effect. A key unresolved chall…
Experimental confirmation of the magnetic ordering transition induced by an electronic structure change in the metallic triangular antiferromagnet CoTaS
Han-Jin Noh, En-Jin Cho, Byeong-Gyu Park +6
We report ARPES studies combined with DFT+DMFT calculations to confirm that the magnetic ordering vector transition from \textbf{Q}=(1/2,0,0) to \textbf{Q}=(1/3,0,0) in the metalli…
Tunable chiral and nematic states in the triple-Q antiferromagnet CoTaS
Erik Kirstein, Pyeongjae Park, Woonghee Cho +3
Complex spin configurations in magnetic materials, ranging from collinear single-Q to noncoplanar multi-Q states, exhibit rich symmetry and chiral properties. However, their detail…
Kitaev interaction and proximate higher-order skyrmion crystal in the triangular lattice van der Waals antiferromagnet NiI2
Chaebin Kim, Olivia Vilella, Youjin Lee +14
Topological spin textures, such as magnetic skyrmions, are a spectacular manifestation of magnetic frustration and anisotropy. Most known skyrmion systems are restricted to a topol…
Spin dynamics of triple-Q magnetic orderings in a triangular lattice: Implications for multi-Q orderings in general two-dimensional lattices
Pyeongjae Park, Woonghee Cho, Chaebin Kim +7
Multi-Q magnetic structures on two-dimensional (2D) lattices provide a key route to realizing topological physics in 2D magnetism. A major experimental challenge is to unambiguousl…
Electrical control of topological 3Q state in intercalated van der Waals antiferromagnet Cox-TaS2
Junghyun Kim, Kai-Xuan Zhang, Pyeongjae Park +4
Van der Waals (vdW) magnets have opened a new avenue of opportunities encompassing various interesting phases. Co1/3TaS2-an intercalated metallic vdW antiferromagnet-is one of the…
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…
