Abstract
Based on Green's function formalism, the existence of multiple mobility edges in a one-dimensional magnetic-non-magnetic superlattice geometry in presence of external electric field is predicted, and, it leads to the possibility of getting a metal-insulator transition at multiple values of Fermi energy. The role of electric field on electron localization is discussed for different arrangements of magnetic and non-magnetic atomic sites in the chain. We also analyze that the model quantum system can be used as a perfect spin filter for a wide range of energy.
