Magnetometry of Novel 2-D Materials
Abstract
The ability to map magnetic field distributions with high sensitivity and nanoscale resolution is of crucial importance for fundamental studies ranging from material science to biology, as well as for the development of new applications in spintronics and quantum technology. In recent years, stray magnetic field mapping has been accomplished by methods such as SQUID, magneto-optical detection, and magnetic force microscopy. However, due to the perturbative nature of the probes, along with loss in sensitivity at elevated temperatures, these techniques provide limited scope to investigate magnetic samples in their native and unprepared state. In contrast, magnetometry with nitrogen vacancy defects in a scanning configuration at cryogenic environment has provided a route to investigating low-dimensional magnetic materials without introducing any significant magnetic perturbation on the probed sample. In this project, we wish to extend this technique to investigate exfoliated 2D magnetic materials and probe the magnetic field dynamics under varying magnetic field and temperature.
