Magnetic Response in Mesoscopic Rings and Moebius Strips: A Theoretical Study
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 Ne, system size N and disorder strength W. Our exact analysis may provide some important signatures to study magnetic response in nano-scale loop geometries.
