摘要：

Ni-Zn-Co ferrite films were deposited by the spin-spray ferrite plating from an aqueous solution. Film with optimized Zn and Co contents (i.e., Ni0.22Zn0.52Co0.03Fe2.23O4) exhibited the real permeability mu'(r) higher than 260 at frequencies up to 130 MHz, and the imaginary permeability mu"(r) higher than 100 in the extremely wide frequency range from 100 MHz to 1 GHz. Prepared at the very low temperature of 90degreesC without postdeposition annealing, these films are promising to be actually applied to electromagnetic noise suppressors which directly cover the noise source elements on printed circuit boards.
