Abstract
We performed electrical transport measurements in strong tilted magnetic fields (up to 30 T) on a high quality bilayer graphene sample. The possibility of tuning the system into a topological state at zero filling factor, associated to a ferromagnetic phase, is demonstrated on the basis of an insulator-to-metal transition and simultaneous arising of strong non-local response. Based on recent theoretical predictions, relevant aspects of the phase transition are quantitatively extracted. New experimental developments on the topics are proposed in the final section.
