Anomalous Corridor impact in edge-bonded monolayer graphene


Anomalous Corridor impact (AHE) is normally presumed to be absent in pristine graphene attributable to its diamagnetism. On this work we report {that a} gate-tunable Corridor resistance Rxy might be obtained in edge-bonded monolayer graphene with out exterior magnetic discipline. In a perpendicular magnetic discipline, Rxy consists of a sum of two phrases: one from extraordinary Corridor impact and the opposite from AHE (RAHE). Plateaus of Rxy ~ 0.94 h/3e2 and RAHE ~ 0.88 h/3e2 have been noticed whereas the longitudinal resistance Rxx lower at temperature of two Ok, that are indications of quantum model of AHE. At temperature of 300 Ok, Rxx reveals a optimistic, large magnetoresistance ~177% and RAHE nonetheless has a worth ~400 Ω. These observations point out the existence of a long-range ferromagnetic order in pristine graphene, which can result in new functions in pure carbon-based spintronics.
