摘要：

Fe and Al co-doped ZnO nanoparticles have been synthesized by sol-gel method and annealed in air and vacuum atmospheres. The results of structural characterization show that the samples have wurtzite structure with no other impurity phases and the doping atoms have not disturbed the hexagonal lattice. Resistivity measurement confirms good conductivity through vacuum annealing. Furthermore, by investigating the magnetic properties, room temperature ferromagnetism has been observed. The saturation magnetization goes up to 1.4 emu/g by sintering the nanoparticles under vacuum. The results suggest that oxygen vacancies play the most important role in mediating the ferromagnetism.
