Abstract

We investigate magnetic response in mesoscopic rings and moebius strips penetrated by magnetic flux ϕ. Based on a simple tight-binding framework all the calculations are performed numerically which describe persistent current and low-field magnetic susceptibility as functions of magnetic flux ϕ, total number of electrons N_e, system size N and disorder strength W. Our exact analysis may provide some important signatures to study magnetic response in nano-scale loop geometries.
