Abstract

The magnetic properties of quantum dots on a graphene nanoribbon are investigated in the context of the method of the generalized gradient approximation of spin-polarized density functional theory. It is shown that the antiferromagnetic ordering of magnetic moments is most stable for ribbons with periodic alternation of graphene-graphane nanosegments. When the graphene nanoribbon is separated by the rows of C atoms with hydrogen atoms adsorbed on them in the form of a two-periodic superlattice, the ferrimagnetic ordering in the coupled unequal quantum dots turns out to be most favorable.
