dc.description.abstract | Of fundamental interest in the field of spintronics is the mechanism of indirect exchange coupling between
magnetic impurities embedded in metallic hosts. A range of physical features, such as magnetotransport and
overall magnetic moment formation, are predicated upon this magnetic coupling, often referred to as the
Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction. Recent theoretical studies on the RKKY in graphene
have been motivated by possible spintronic applications of magnetically doped graphene systems. In this paper
a combination of analytic and numerical techniques are used to examine the effects of defect dimensionality
on such an interaction. We show, in a mathematically transparent manner, that moving from single magnetic
impurities to extended lines of impurities effectively reduces the dimensionality of the system and increases the
range of the interaction. This has important consequences for the spintronic application of magnetically-doped
systems, and we illustrate this with a simple magnetoresistance device. | en |
