摘要：
We examine the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction between two local spins embedded in an Aharonov-Bohm (AB) ring. The flux-dependent RKKY interaction dominates the transport properties for both ferromagnetic and antiferromagnetic coupling. For ferromagnetic coupling, the amplitude of AB oscillations is enhanced by Kondo correlations and for antiferromagnetic coupling the phase of AB oscillations is shifted by pi. (c) 2006 Elsevier B.V.
