Study on Magnetism of Defective Reduced Graphene Oxide (rGO)

Abstract: Reduced graphene oxide (rGO) is a fascinating system having significant defects and functional group on its sheets, hence provides an ideal playground to raise magnetism of intrinsically nonmagnetic graphene. rGO have been reported to exhibit various magnetic states, in which their origin has been believed to be related with defect states in the rGO sheet. An enhancement in magnetization with a small magnetic hysteresis was observed in rGO when the amount of defect increases confirming defect induced magnetism in the samples. Our previous µSR data indicate a feature of the appearance of oscillation component on top of the decaying signal in the time spectra. However, with the current data we are still not able to confirm whether the feature is related to the formation of magnetic ordering or of a Mu-H entangled state. Therefore,we propose further µSR measurements on rGO for clarification
