Study of the indirect exchange interaction in a strained graphene nanoribbon

In this paper we study the indirect exchange interaction in a strained graphene ribbon of finite width within a frame of the s-d model. Our calculations show that magnetic ordering of the spins of impurities varies periodically with increasing distance between atoms and asymptotically tends to zero. We analyze the dependence of the exchange interaction on the directions of deformation in the film, as well as on the external magnetic field.
