Spatial correlations of charge density wave order across the transition in 2H-NbSe2
Seokjo Hong, Jaewhan Oh, Jemin Park +7
Charge density waves (CDWs) involve coupled amplitude and phase degrees of freedom, but direct access to local amplitude correlations remains experimentally challenging. Here, we r…

Polymorphic spin ordering in a single-crystalline cobalt-doped Fe3GaTe2
Woohyun Cho, Jaehun Cha, Yoon-Gu Kang +10
A single crystalline system typically stabilizes a unique state for spin ordering below a critical temperature. Certain materials exhibit multiple magnetic states, driven by struct…
