【 摘 要 】

Nanoferrites with a composition of Ni0.35Zn0.35Co0.2Mn0.05Cu0.05Fe1.98O4 were synthesized by a co-precipitation method. The material obtained after sintering at 900 degrees C shows almost matching permeability and permittivity values of close to 6 with low values for magnetic loss tangent (similar to 0.03) and dielectric loss tangent (similar to 0.008) in the range 10-200 MHz. Together with a refractive index of about six and a reduced impedance of around one, this material could be employed for loading of miniaturized antennas in the VHF band.
