摘要
Mn doped ZnO Dilution Magnetic Semiconductors (DMSs) samples with nominal composition Zn0.993Mn0.007O were fabricated by chemical method. The structural and magnetic properties as well as optical properties of the synthesized samples were studied. The results indicated that samples sintered at temperatures below 600°C showed a single wurtzite ZnO structure with prominent ferromagnetism at room temperature, while sample sintered at 800°C a second phase, namely, ZnMnO3 observed with significant reduced ferromagnetism and an enhancement of paramagnetism. Structural and optical properties study demonstrated that the ferromagnetism observed in the studied samples was originated from the doping of Mn in the lattice of ZnO crystalline, which confirmed intrinsic room temperature ferromagnetism in (ZnMn)O crystal.
