Abstract

Using first principles calculations based on the density functional theory and generalized gradient approximation we show that the ground state of Mn doped ZnO (101¯0) thin film changes from antiferromagnetic to ferromagnetic when codoped with N. The ferromagnetic coupling between Mn spins arises due to the overlap between N 2p and Mn 3d electrons in the spin up band, rendering the system half-metallic character.
