| Abstract: | Magnetometer is one of the primary sensors in geophysics.A massive of interest has been attracted by Graphene these years,for its potential of developing various types of sensors.The need of higher sensitvity and smaller scale of magnetometers,may be met by the ultra-thin body and huge specific surface area due to the quasi-two-dimensional structure of graphene.The stable thermal and dynamical characteristics of graphene may also improve the stablization and consistency of the magnetometers.This paper makes a summarize of the experiments and applications of graphene magnetometers,as well as their principle and performance,including graphene Hall elements,Extraodinary Magnetoresistance(EMR)devices,graphene SQUIDs,and fiber-optic Lorentz force magnetometer based on a gold-graphene composite membrane,etc. |
