Abstract	Cadmium oxide (CdO) nanopowders doped with Cu/Fe were synthesised by co-decomposition of method of complexes to examine that Cu ion doping behaves as a “magneto-catalyst”, which enhances the magnetic properties of 1 wt.% Fe-doped CdO. Furthermore, the effect of annealing in air, vacuum and hydrogen atmosphere was also investigated. The analysis confirms the formation of single CdO phase for as-prepared and vacuum-annealed compositions, whereas Cd metal appeared after annealing in H$_{2}$. An enhancement of the saturation magnetisation by the presence of Cu ions was obtained, 2.93 and 5.50 memu/g, for CdO:Fe and CdO:Cu:Fe, respectively. It was found that annealing in H$_{2}$ resulted in tremendous increase of M$_{s}$, reaching very high values of 837 and 594 memu/g for H-treated compared to as-prepared CdO-Fe and CdO-Cu-Fe, respectively.
