美国马里兰大学的研究人员最近发现,在石墨烯晶格中人为地、有控制地引入晶格缺陷,可以产生局部磁场,这些磁场对传导电子散射几率的影响类似于参杂金属晶体中产生的近藤效应。研究人员希望这一发现使得石墨烯可以被用来制造磁传感器和磁阻随机存储器。 Researchers at the University of Maryland recently discovered that artificially and controlled introduction of lattice defects into the graphene lattice can produce localized magnetic fields that have a similar effect on the probability of scattering of conductive electrons as Kondo effect. The researchers hope this discovery makes graphene can be used to make magnetic sensors and magnetoresistive random access memory.
