Abstract

Dilute magnetic semiconductors (DMSs), exhibiting both semiconducting and magnetic properties, are interesting materials for novel spintronic devices. Because of the giant Zeeman effect in the paramagnetic state, non-uniform magnetic fields can manipulate the spin texture of carriers in the DMS. A tight-binding model is developed to describe the energy bands formed due to the magnetic field associated with a type-II superconducting film above a DMS layer. Magnetic flux concentrated at the edges of superconducting disks and rings above DMS layers is shown to result in edge-confined states.
