摘要：

We have observed anomalous temperature dependence of magnetization of ZnSnAs2: Mn epitaxial thin films grown on InP(001) substrates compared with the values estimated by the meanfield theory using S = 5/2, as a function of temperature: The ZnSnAs2:Mn epitaxial thin films exhibits slightly increasing magnetization with rising temperature. From the first-principles calculation, when Mn substitutes for neighboring Zn sites in ZnSnAs2, Mn-Zn-Mn-Zn pairs result, which prefer antiferromagnetic (AFM) ordering. On the other hand, Mn-Zn-Mn-Sn and Mn-Sn-Mn-Sn pairs can introduce both holes and spins, leading to ferromagnetic (FM) ordering. Thus, assuming that the magnetic property of ferromagnetic phase follows the mean-field theory, it can be explained by coexistence of FM and AFM phases.
