Altermagnetism produces pair emission and absorption from dark excitons and magnons in LaOMnSe

Birender Singh, Xian Xu, Sabrina R. Hatt +21

Altermagnets' (AMs) non-relativistic spin splitting enables novel states, spintronic and magneto-optical devices, though their optical signatures remain elusive. Here, we report ex…

Scalable and deterministic construction of moiré superlattice in 2D materials using stressor films

Yu-Mi Wu, Sihun Lee, Yufeng Xi +6

Moiré superlattice in two-dimensional (2D) materials provides a powerful platform to engineer emergent electronic states, yet the construction of moiré superlattices remains lab-sc…

Unraveling nano-scale effects of topotactic reduction in LaNiO crystals

Yu-Mi Wu, Pascal Puphal, Masahiko Isobe +4

Infinite-layer nickelates stand as a promising frontier in the exploration of unconventional superconductivity. Their synthesis through topotactic oxygen reduction from the parent…

Topotactically induced oxygen vacancy order in nickelate single crystals

Yu-Mi Wu, Pascal Puphal, Hangoo Lee +6

The strong structure-property coupling in rare-earth nickelates has spurred the realization of new quantum phases in rapid succession. Recently, topotactic transformations have pro…

Topotactic transformation of single-crystals: from perovskite to infinite-layer nickelates

Pascal Puphal, Yu-Mi Wu, Katrin Fürsich +9

Topotactic transformations between related crystal structures are a powerful emerging route for the synthesis of novel quantum materials. Whereas most such "soft chemistry" experim…
