Magnetic Response in Mesoscopic Rings and Moebius Strips: A Theoretical Study

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.
