Multiferroic-enabled magnetic exciton in 2D quantum entangled van der Waals antiferromagnet NiI2
Suhan Son, Youjin Lee, Jae Ha Kim +15
Matter-light interaction is at the center of diverse research fields from quantum optics to condensed matter physics, opening new fields like laser physics. A magnetic exciton is o…
Highly efficient nonvolatile magnetization switching and multi-level states by current in single van der Waals topological ferromagnet Fe3GeTe2
Kaixuan Zhang, Youjin Lee, Matthew J. Coak +10
Robust multi-level spin memory with the ability to write information electrically is a long-sought capability in spintronics, with great promise for applications. Here we achieve n…
Gigantic current control of coercive field and magnetic memory based on nm-thin ferromagnetic van der Waals Fe3GeTe2
Kaixuan Zhang, Seungyun Han, Youjin Lee +11
Controlling magnetic states by a small current is essential for the next-generation of energy-efficient spintronic devices. However, it invariably requires considerable energy to c…
Possible persistence of multiferroic order down to bilayer limit of van der Waals material NiI
Hwiin Ju, Youjin Lee, Kwang-Tak Kim +10
Realizing a state of matter in two dimensions has repeatedly proven a novel route of discovering new physical phenomena. Van der Waals (vdW) materials have been at the center of th…
