Scanning Magnetometry of Low Dimensional Electronic Systems
Abstract
The project successfully built and qualified a scanning probe microscope for magnetic and thermal imaging that operates at temperatures between 1.6-7.2K and in magnetic fields up to several tesla. We have used this to image a variety of materials, most notably atomically thin insulating ferromagnets, with one paper in preparation. We have also, in the course of our studies of twisted graphene heterostructures, made a major discovery of a new form of orbital magnetism supporting quantized electrical transport at zero magnetic field. This latter has far reaching applications for resistance metrology as well as ultra-low power electrically switchable magnetic memory storage.
