Abstract
We have investigated the electronic structure and magnetic properties of Na and Mn codoped CaZn2As2 using density functional theory within the generalized gradient approximation (GGA)+U schemes. We have shown that the ground state magnetic structure of Mn-doped CaZn2As2 is antiferromagnetic while holemediated Zener’s p–d exchange is responsible for the origin of ferromagnetism of Na and Mn codoped CaZn2As2.
