Implication

Nonlocal transport measurements reveal strong magnetic field-induced chiral responses in graphene superlattices, suggesting new pathways for orbitronic devices.

Key Points

Chiral responses emerge under magnetic fields in small-gap moiré superlattices, remaining stable up to sizable temperatures with distinct sign dependence.
Nonlocal transport measurements supported by numerical simulations detect transverse flow of orbital information, showing clear magnetic field orientation effects.
Generation of orbital magnetic moments via the orbital Hall effect may enable orbitronic devices, expanding electronic manipulation beyond charge and spin.
