Unconventional and Fragile Magnetic Exciton in a van der Waals Quantum Magnet
Kai-Xuan Zhang, Min Zhang, Minjae Kim +25
The study investigates a magnetic exciton in the van der Waals antiferromagnet NiPS3, showing that its sharp, optically bright emission is quickly quenched by modest hydrostatic pr…
Fragility of Topology under Electronic Correlations in Iron Chalcogenides
Younsik Kim, Junseo Yoo, Sehoon Kim +5
The interplay between electronic correlations and topology is a central topic in the study of quantum materials. In this work, we investigate the impact of the orbital-selective Mo…
Low-dimensionality-induced tunable ferromagnetism in SrRuO ultrathin films
Jinyoung Kim, Minjae Kim, Donghan Kim +5
Quantum materials near electronic or magnetic phase boundaries exhibit enhanced tunability, as their emergent properties become highly sensitive to external perturbations. Here, we…
Microscopic origin of the spin-splitting in altermagnets
Suyoung Lee, Minjae Kim, Changyoung Kim
Altermagnets, characterized by spin-split bands without net magnetization, have recently emerged as a promising platform for spintronics. However, their microscopic mechanisms rema…
Strain Engineering of van Hove Singularity and Coupled Itinerant Ferromagnetism in Quasi-2D Oxide Superlattices
Seung Gyo Jeong, Minjae Kim, Jin Young Oh +12
Engineering van Hove singularities (vHss) near the Fermi level, if feasible, offers a powerful route to control exotic quantum phases in electronic and magnetic behaviors. However,…
