## Description

- description: Graphene-based superlattices offer a new materials playground to exploit
    and control a higher number of electronic degrees of freedom, such as charge,
    spin, or valley in disruptive technologies. Recently, orbital effects, emerging
    in multivalley band structure lacking inversion symmetry, have been discussed
    as possible new phenomena for developing orbitronics. Here, we report non- local
    transport measurements in small gap hBN/graphene/hBN moiré superlattices which
    reveal very strong magnetic field-induced chiral response which is stable up to
    room temperature. The measured sign dependence of the non-local signal with respect
    to the magnetic field orientation clearly indicates strong interaction with orbital
    magnetic moments. Our analysis confirms that such emerging orbital effects can
    be manipulated by magnetic and electric fields which respectively lift the valley
    degeneracy and generate transverse flow of valley-dependent orbital magnetic moments.
    The interpretation of experimental data is well supported by numerical simulations,
    and the reported phenomenon is a formidable way of in-situ manipulation of the
    transverse flow of orbital information, that could enable developing (spin)-orbitronic
    devices.
