چکیده انگلیسی
Nanosized Ni0.70Zn0.25Co0.05Fe1.90Mn0.02O4 ferrite ceramics were fabricated from high-energy ball milled powder mixtures with various ratios of Fe2O3/Fe as starting materials, in order to achieve magneto-dielectric materials with near net shape behavior for practical applications. The ferrite ceramics were obtained by sintering the milled powder compacts at 800â¯Â°C for 4â¯h, with a linear expansion of less than 4% as compared to the green pellets. The ceramics had an average grain size of less than 200â¯nm. The real part of relative permittivity decreases with increasing percentage of Fe2O3 used in the starting mixtures. The sample from the powder mixture with 50% Fe2O3 exhibits promising magneto-dielectric properties at frequencies of up to 90â¯MHz, which can be used for miniaturization of antennas at very high frequency (VHF) band.
