Abstract

Abstract: In this work, we have studied the effect of magnetic atom doping of graphene structure using Monte Carlo simulation. The reduced critical temperature with the magnetic atom doping x has been deduced from the thermal variation of magnetization and magnetic susceptibility. The variation of magnetization versus the crystal field of grapheme structure for different x and for different reduced temperatures has been established. We also have measured the coercive field (hC ) as a function x in grapheme structure, finding that hC increases with increasing x concentration as predicted experimentally. The doping-induced magnetism in graphene. Magnetically atom doping in graphene systems are potential candidates for application in future spintronic devices, magnetometry requires macroscopic quantities of graphene to detect magnetic moments directly. Highlights: Magnetically-vacancy graphene systems are studied by Monte Carlo simulation. The reduced critical temperature with the vacancy x has been deduced. The magnetic coercive field versus the vacancy x of grapheme structure has been obtained. Magnetically-vacancy in graphene is potential candidate for application in future spintronic devices.
