Discovering Magnetic Graphene Paves a Way to Spintronics – The Foundation for Next-generation Energy-efficient Information Processing

Researchers in Professor Sakhrat Khizroev group at Florida International University teamed up with Dr. Jeongmin Hong at the UC Berkeley, Professor Robert Haddon at UC-Riverside, and Professor Walt de Heer at Georgia Institute of Technology to experimentally demonstrate (for the first time) the presence of magnetic properties in functionalized graphene nanostructures at room temperature. Their study was presented in ACS Nano on October 28. The demonstration of magnetic properties opens a window for new applications of graphene in the emerging field of Spintronics, which promises to revolutionize next-generation information processing. Spintronics is often viewed also as a stepping stone towards Quantum Computing with its hallmark applications including infinitely fast computation with infinitely large memory and with almost zero energy consumption. Due to the enormous potential, the search for magnetic properties in graphene has been one of the most important scientific frontiers across the globe. The main challenge is to establish stable long-range magnetic states in 2-D graphene systems.  This multi-university and cross-disciplinary team overcame this challenge by using refined functionalization chemistry to induce interacting magnetic spins in 1- and 2-dimensional graphene nanostructures.  The project was supported through National Science Foundation (NSF) Materials Research Science and Engineering Center (MRSEC) “Graphene-based Nanoelectronics” at Georgia Tech. This work is a continuation of the original research by the same team from a few years ago (published in Scientific Reports).
