Thesis title: The Next Generation of Magnetoresistive Materials
Magnetic field sensors with ultra-high sensitivities are desirable for applications as diverse as biomedicine, scanning magnetometry, and data storage. In my project we are aiming to leverage the unique electronic properties of atomically-thin materials such as graphene to produce magnetoresistive devices where the measured resistance varies dramatically as a function of the magnetic flux density. The working principle of these devices is a phenomenon known as extraordinary magnetoresistance, an effect that arises from the way in which the Lorentz force affects the motion of charge carriers in an inhomogenous material system. If the project is successful, the devices will be used to measure the minute magnetic fields produced by living neurons.
