In this paper, a correlation between structural and magnetic properties of Fe-implanted ZnO is presented. High fluence Fe + implantation into ZnO leads to the formation of superparamagnetic α-Fe nanoparticles. High vacuum annealing at 823 K results in the growth of α-Fe particles, but the annealing at 1073 K oxidizes the majority of the Fe nanoparticles. After a long term annealing at 1073 K, crystallographically oriented ZnFe 2 O 4 nanoparticles are formed inside ZnO with the orientation relationship of ZnFe 2 O 4 (1 1 1)[1 1 0]//ZnO(0 0 0 1)[11 2 0]. These ZnFe 2 O 4 nanoparticles show a hysteretic behaviour upon magnetization reversal at 5 K.
