Electrical switching of magnetic order in an orbital Chern insulator
Hryhoriy Polshyn, Jihang Zhu, Manish A. Kumar +8
Magnetism typically arises from the joint effect of Fermi statistics and repulsive Coulomb interactions, which favors ground states with non-zero electron spin. As a result, contro…

Intrinsic quantized anomalous Hall effect in a moiré heterostructure
M. Serlin, C. L. Tschirhart, H. Polshyn +6
We report the observation of a quantum anomalous Hall effect in twisted bilayer graphene showing Hall resistance quantized to within .1\% of the von Klitzing constant at ze…
