Abstract ：We have investigated a new ferrite-ceramic composite material with inductive and capacitive properties fabricated by a solid-state reaction method. We analyse the effects of composite mechanism and microstructure on the magnetic and electric properties. The results show that the new materials can be used as not only the inductor materials, but also the capacitor materials in a wide frequency range of 1 kHz-1.8 GHz. The real part of permeability of the composite material is between 10 and 5.6, the imaginary part of permeability is between 1.2 and 0.5, and the dielectric constant is about ten times larger than the ordinary ferrite materials. It is suggested that the new composite materials will be widely used in anti-electromagnetic interference fields and radio frequency communication fields.
