- Title
Ferromagnetic origin of Na and Mn codoped CaZnAs diluted magnetic semiconductor: A first-principles study.

- Abstract
We have investigated the electronic structure and magnetic properties of Na and Mn codoped CaZnAs using density functional theory within the generalized gradient approximation (GGA)+U schemes. We have shown that the ground state magnetic structure of Mn-doped CaZnAs is antiferromagnetic while holemediated Zener's p- d exchange is responsible for the origin of ferromagnetism of Na and Mn codoped CaZnAs.
