Creation of localized spins in graphene by ring-opening of epoxy derived hydroxyl

Creation of high-density localized spins in the basal plane of graphene sheet by introduction of sp(3)-type defects is considered to be a potential route for the realization of high-magnetization graphene. Theoretical and experimental studies confirmed that hydroxyl can be an effective sp(3)-type candidate for inducing robust magnetic moment. However, the artificial generation of hydroxyl group...

Graphene Edge Spins: Spintronics and Magnetism in Graphene Nanomeshes

We have fabricated low-defect graphene nanomeshes (GNMs) by using a non-lithographic method and observed large-amplitude ferromagnetism even at room temperature, only when pore edges of the GNMs were hydrogenterminated. The observed correlation between the inter-pore spacing and magnetism and also magnetic force microscope observations suggest that it is attributed to polarzied electron spins l...

The classical and quantum dynamics of molecular spins on graphene

Controlling the dynamics of spins on surfaces is pivotal to the design of spintronic and quantum computing devices. Proposed schemes involve the interaction of spins with graphene to enable surface-state spintronics and electrical spin manipulation. However, the influence of the graphene environment on the spin systems has yet to be unravelled. Here we explore the spin-graphene interaction by s...

Spins and Phonons in Graphene Nanostructures

Quantum information science relies on quantum systems with sufficiently long coherence times. A spintronics implementation in graphene would benefit from the low density of nuclear spins in carbon and small spin-orbit interactions. The coupling of the spin to lattice dynamics puts an upper bound on spin coherence times. In addition, phonons in graphene are interesting due to the monatomic thick...
