Multiferroicity in the two-dimensional limit in hexagonal LuFeO3 films
Huilin Lai, Junyu Tan, Jinfeng Zhai +15
Multiferroic oxides, which combine coupled ferroelectric and magnetic orders, are central to understanding correlated quantum phenomena. Yet, as thickness approaches the two-dimens…
Giant field-tunable nonlinear Hall effect by Lorentz skew scattering in a graphene moire superlattice
Pan He, Min Zhang, Yue-Xin Huang +13
The nonlinear Hall effect (NHE) can enable rectification and energy harvesting, and its control by external fields, including gate, strain and magnetic field, has been pursued inte…
Sign reversal of Berry curvature triple driven by magnetic phase transition in a ferromagnetic polar metal
Xuyang Sha, Xuejin Zhang, Hao Liu +10
While the time-reversal-even (T-even) nonlinear Hall effect has been extensively discussed in nonmagnetic materials, the impact of magnetic phase transition on it remains largely o…
Observation of giant nonlinear valley Hall effect
Pan He, Min Zhang, Jin Cao +7
The valley Hall effect (VHE) holds great promise for valleytronic applications by leveraging the valley degree of freedom. To date, research on VHE has focused on its linear respon…
