Optimization of Ni0.95−xZnxCo0.05Fe1.90Mn0.02O4 ceramics with promising magneto-dielectric properties for VHF antenna miniaturization

Magnetic, dielectric and DC conductive properties of Ni0.95−xZnxCo0.05Fe1.90Mn0.02O4 (with x=0-0.20 at an interval of 0.05) ferrite ceramics were studied, in order to develop magneto-dielectric materials with almost equal values of relative permeability and permittivity, for the miniaturization of H...
