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…
The field-angle anisotropy of proximate Kitaev systems under an in-plane magnetic field
Beom Hyun Kim
We have investigated the field-angle behaviors of magnetic excitations under an in-plane magnetic field for proximate Kitaev systems. By employing the exact diagonalization method…
Exciton-driven antiferromagnetic metal in a correlated van der Waals insulator
Carina A. Belvin, Edoardo Baldini, Ilkem Ozge Ozel +11
Collective excitations of bound electron-hole pairs -- known as excitons -- are ubiquitous in condensed matter, emerging in systems as diverse as band semiconductors, molecular cry…
Modulating Curie Temperature and Magnetic Anisotropy in Nanoscale Layered Cr_{2}Te_{3} Films: Implications for Room-Temperature Spintronics
In Hak Lee, Byoung Ki Choi, Hyuk Jin Kim +18
Nanoscale layered ferromagnets have demonstrated fascinating two-dimensional magnetism down to atomic layers, providing a peculiar playground of spin orders for investigating funda…
Interplay between multipolar spin interactions, Jahn-Teller effect and electronic correlation in a insulator
Dario Fiore Mosca, Leonid V. Pourovskii, Beom Hyun Kim +5
In this work we study the complex entanglement between spin interactions, electron correlation and Janh-Teller structural instabilities in the 5d spin-orb…
Electric field driven octahedral rotation in perovskite
Wonshik Kyung, Choong H. Kim, Yeong Kwan Kim +9
Rotation of MO6 (M = transition metal) octahedra is a key determinant of the physical properties of perovskite materials. Therefore, tuning physical properties, one of the most imp…
