Two-dimensional materials-based spintronic devices

Nanomagnetism and spintronics are fast evolving, competitive research areas worldwide. Research in these fields is highly motivated by the large potential for applications. Field sensors, magnetic random access memory, data storage, magnetic logic, transistors and microwave components are examples of applications that drive numerous studies. Magnetic domain walls (DWs) in nanostructures are low-dimensional objects that separate regions with uniform magnetization. DWs have interesting properties for spintronics and researchers envision to use them in the next generation of magnetic memories. The purpose of the PhD thesis is to implement, for the first time, high-quality magnetic structures based on 2D materials (e.g., graphene) into lab-scale spintronic devices, in which an electric current will be injected to manipulate and move DWs.

The novelty of our approach is to partly replace expensive and strategic transition metals used in all existing actual spintronic devices by a single layer of an abundant element (e.g., carbon in graphene). These devices may perform faster than actual technology, with lower energy consumption while relying on sustainable, low cost materials.
