Spatial dependence of the superexchange interactions for transition-metal trimers in graphene
Charles B. Crook, Gregory Houchins, Jian-Xin Zhu +3
This study examines the magnetic interactions between spatially-variable manganese and chromium trimers substituted into a graphene superlattice. Using density functional theory, w…
Voltage-dependent spin flip in magnetically-substituted graphene nanoribbons: Toward the realization of graphene-based spintronic devices
Gregory Houchins, Charles B. Crook, Jian-Xin Zhu +2
We examine the possibility of using graphene nanoribbons (GNRs) with directly substituted chromium atoms as spintronic device. Using density functional theory, we simulate a voltag…
Proximity-induced magnetism in transition-metal substituted graphene
Charles B. Crook, Costel Constantin, Towfiq Ahmed +3
We investigate the interactions between two identical magnetic impurities substituted into a graphene superlattice. Using a first-principles approach, we calculate the electronic a…
