ABSTRACT:
A ferromagnetic metal/ceramic composite comprising particles of ferromagnetic metal embedded within an insulating ceramic has high electrical resistivity and high saturation magnetization. The composite is prepared by sputtering in a mixture of a nonreactive gas with a reactive gas, followed by annealing.
