Greatly enhanced magnetic properties of electrodeposited Ni–Co–P–BaFe12O19 composites

We prepared electrodeposited Ni–Co–P–M-type BaFe12O19 (BaM) film as magnetic soft–hard composites with a large amount of entrapped BaM particles more than 40 wt% were grown over polycrystalline copper substrates. The results show that the saturation magnetization of BaM particles remarkably increases by more than 300% and Mr increases by more than 700% when they embedded into the Ni–Co–P metal. In contrast to previous reports, it is clear that values of coercivity and squareness for our work are significantly better than corresponding values obtained for electrodeposited Ni–Co–BaM composite films of previous works.
