Spin Electronics technology will enable a revolutionary class of electronic devices. Gallium nitride (GaN) containing transition metals (TM) (eg Mn, Ni and Fe) is a very promising dilute magnetic semiconductor for practical spintronics applications as this material exhibits magnetic behaviour above room temperature. However, electronic and magnetic properties of this new class of semiconductors have not yet been optimised.
