We have investigated the electronic structure and magnetic properties of Ba and Mn co-doped LaZnAsO using density functional theory within the generalised gradient approximation (GGA)+U schemes. We have shown that the ground state magnetic structure of Mn-doped LaZnAsO is antiferromagnetic while Ba and Mn co-doped LaZnAsO is ferromagnetic. The origin of the Mn-Mn exchange mechanism is discussed.
