This dataset, provided by Wang et al. in 2026 for the study "High-Chern-number orbital magnetism in twisted rhombohedral graphene," contains 62 plain text files that support the main findings of the paper. The files include experimental measurements such as Rxx and Ryx data, as well as parameters D and nu corresponding to Figures 2a through 2f, allowing for the analysis of transport and magnetic properties in twisted rhombohedral graphene systems.
