摘要：

ZnO doped with Co has been synthesised at various concentrations from 1 to 20 atom % in bulk polycrystalline form by wet chemical method. Particle size was ranging from 40-50nm. There was a signature of ferromagnetism at 7 atom % and higher with S-type curves in M-H plots. Remanent magnetization was quite appreciable. But, there is anomaly with decrease in moment at higher atomic concentrations. No sign of superparamagnetism due to nanoparticles was there. Magnetism is thought to be due to interaction between nearest neighbor Co(II) ions along with clusters of Co(II) in isolation, which may be due to precipitation.
