N2 - The energy spectra and magnetization for a system consisting of vertically coupled nanoscale semiconductor quantum rings (VCNSQR) under an external magnetic field was investigated. In this system, the electron moves in a 3D torus confinement region and tunnels among stacked layers which complicates the electron structure of the system. Nonlinear iterative method was used to compute energy states and magnetization for the vertically 2-coupled nanoscale InAs/GaAs quantum rings. It was observed that the magnetization of the quantum rings has a non periodical oscillation, where each non periodical jump relates to the crossing of single electron states and changes in the ground states.
