摘要: Abstract First principle calculations were performed to study the effect of Mn-Mn separation and hole carrier on magnetic properties Li(ZnMn)As. The was introduced by co-doping with Cu or C at site Zn As, respectively. results showed that Mn atoms preferred short-range antiferromagnetic stability for their superexchange interactions. additional induced transition ground states from ferromagnetic, which benefit carrier-mediated double exchange p-d mechanisms. values energy difference exhibited plateau behavior separation, indicating promoted long-range ferromagnetic stability, ordering system enhanced increase concentration.
