The magnetic property of Mn-Zn ferrite has been modified by Si+ and Au+ implantation at 3 MeV to doses of 1×1016 and 1×1017 cm-2, respectively. The magnetization of the implanted surface layer decreased to zero when the ion implantation induced vacancy number was high enough. The decrease in magnetization is found to be related to the vacancy number in the implanted layer. The surface magnetization of the implanted layer can be completely recovered by thermal annealing at 850°C for 30 min.
