From: Robust magnetic moments on the basal plane of the graphene sheet effectively induced by OH groups
Robust magnetic moments induced by OH groups on the basal plane of graphene sheet.
(a) Dependences of spin density (orange circles) and the magnetic inducing efficiency of OH groups (red circles) on the annealing temperature. The solid lines are the guides for the eye only. (b) Schematic illustration of (OH)7 cluster on the basal plane of the graphene sheet and the corresponding spin charge density distribution with contour spacings 1 × 10−2 e/Å3. Carbon, oxygen and hydrogen atoms are yellow, red and cyan, respectively. Capital A denotes the OH group in (OH)7 cluster which sits on sublattice A of graphene sheet. Majority and minority spins are purple and blue, respectively.
