-wave altermagnetic order parameter in hematite
Tianren Wang, Yuehong Li, Yu Feng +11
Altermagnets combine the vanishing net magnetization of antiferromagnets with momentum-dependent spin splitting. Magnon band splitting provides a direct probe of altermagnetic orde…
Strain-tunable charge localization coupled to complex magnetic orders in EuAl
M. Baumgartner, Xunyang Hong, Tianren Wang +19
Charge localization is particularly interesting when coupled to antiferromagnetic spin structures. Coupled spin-charge orders are well established in elemental chromium and correla…
Collective spin excitations in trilayer nickelate LaNiO
Ying Chan, Yuehong Li, Yujie Yan +14
Ruddlesden-Popper (RP) nickelates have recently emerged as a new family of high-temperature superconductors. In bilayer RP nickelates, magnetic excitations with large exchange coup…
Persistent paramagnons in high-temperature infinite-layer nickelate superconductors
Yujie Yan, Ying Chan, Xunyang Hong +25
The recent discovery of high-temperature superconductivity in hole-doped SmNiO, exhibiting the record-high transition temperature among infinite-layer (IL) nickelates, ha…
