The Zn1-xAxO (A = Mn, Fe and x = 0 - 0.03) nanopowders, have successfully been synthesized by coprecipitation method. The starting materials of dihydrate zinc acetate, iron and mangan powders were employed using HCl and NH4OH as solvent and precipitating agents respectively. The solution was stirred at 48°C for 4h to induce a precipitation and the resulted precipitate was then heated at 100°C for 24h in air followed by annealing at 400°C for 3h. Based on the XRD spectra, the doped samples with x up to 0.02 form the single wurtzite phase of ZnO with crystal size around 20-60 nm, where the dopants, both Mn and Fe, have partially substituted Zn. Meanwhile, samples with x = 0.03 were obesrved to contain impurity phases. The magnetization for the magnetic field up to 1 tesla vizualizes a monotonically increased weak-ferromagnetism for Fe doping, while exhibits from diamagnetic, paramagnetic to weak-ferromagnetic behaviors for Mn doping. This magnetic interaction becomes complicated by the presence of magnetic impurities due to Mn dopant.
