Terraced graphene for ultrasensitive magnetic field sensor – Phys.org

National University of Singapore physicists have developed a sensitive two-dimensional (2-D) magnetic field sensor, which can potentially improve the detection of nanoscale magnetic domains for data storage applications.
Magnetoresistance (MR), the change in the electrical resistance of a material due to the influence of an external magnetic field, has been widely used in magnetic sensors, magnetic memories and hard disk drives. However, in traditional three-dimensional (3-D) material-based mag…
