Abstract
In this paper, the magnetic-field dependence of low-lying spectra of a single-electron magnetic quantum ring and dot, formed by inhomogeneous magnetic fields, are calculated using the numerical diagonalization scheme. The effects of on-center acceptor and donor impurities are also considered. In the presence of an acceptor impurity, transitions in the orbital angular momentum, , are found for both the magnetic quantum ring and the magnetic quantum dot when the magnetic field is varied.
