Abstract
The present work is a theoretical study of the electronic properties of alloyed double metal ring (ADMR) threaded by magnetic flux. The system that takes into account in the study is consisting of two rings connected parallel, with two different types of atomic sites. This work having; two parts. The first part a calculation of the energy spectrum, persistent current, Drude weight and low-field magnetic susceptibility of ADMR by the tight-binding method. While the second part is a is a computation of electronic properties of the alloyed double metal ring by density functional theory (DFT). The latter part is considered as a simulation of what was studied in the first part. The results, of our proposed work show that the on-site energies for both types of atoms, inter-ring coupling strength and hopping strengths play an important role in controlling the electronic properties.
