Spintronics/Nanomagnetism
Spintronics (spin electronics) is one of the most promising approaches for next-generation ultra-fast and highly energy-efficient memory, logic, and computing devices. Research in spintronics focuses on understanding how electron spins behave in solid-state materials, including ferro- and ferri-magnets, as well as emerging two-dimensional van der Waals magnetic materials. It also investigates how these spins can be reliably and efficiently manipulated for practical device applications.
The CXRO team is dedicated to advancing spintronics research by addressing critical scientific and technological challenges in the field. Our research primarily employs soft X-ray microscopy and micromagnetic simulations to explore spin phenomena and the physical and topological properties of magnetic and spin structures at the nanoscale.
