摘　　要：磁传感器是地球物理学领域的主要常规测量仪器之一.石墨烯是近年来备受关注的新材料,具有应用到多类高精密传感器的潜力.石墨烯因其准二维结构形成的超薄、超大反应面积,有望使磁传感器测量精度更高、重量更轻.石墨烯稳定的热学和力学性质,也有望提升传感器的稳定性和一致性.本文综述了石墨烯在磁传感器方面的一些应用和试验,介绍了石墨烯霍尔元件、石墨烯巨磁阻传感器、石墨烯超导量子干涉器件、以及石墨烯光导纤维洛伦兹力传感器等的原理及部分特性.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.
