The electronic properties of graphene superlattices have attracted intenseinterest that was further stimulated by the recent observation of novelmany-body states at "magic" angles in twisted bilayer graphene (BLG). For verysmall ("marginal") twist angles of 0.1 deg, BLG has been shown to exhibit astrain-accompanied reconstruction that results in submicron-size triangulardomains with the Bernal stacking. If the interlayer bias is applied to open anenergy gap inside the domain regions making them insulating, marginally-twistedBLG is predicted to remain conductive due to a triangular network of chiralone-dimensional (1D) states hosted by domain boundaries. Here we study electrontransport through this network and report giant Aharonov-Bohm oscillationspersisting to temperatures above 100 K. At liquid helium temperatures, thenetwork resistivity exhibits another kind of oscillations that appear as afunction of carrier density and are accompanied by a sign-changing Hall effect.The latter are attributed to consecutive population of the flat minibandsformed by the 2D network of 1D states inside the gap. Our work shows thatmarginally twisted BLG is markedly distinct from other 2D electronic systems,including BLG at larger twist angles, and offers a fascinating venue forfurther research.
