Abstract:
Mg ferrites with magnetic and dielectric properties are widely used composites to stabilize spinel structure. This study investigates the effect of sintering temperature (900°C, 915°C, 930°C, 945°C, 960°C) on the magnetic and dielectric properties and low-loss characteristics of Mg 0.7 Cd 0.3 Fe 1.92 Ga 0.08 O 4 composites with 5 wt.% Bi 2 O 3 addictive. The change in temperature enhances magnetization (saturation magnetization Ms from 24.37 emu/g to 33.12 emu/g), hence increasing permeability. The real permeability ( μ ’) of Mg-Cd-Ga ferrites was examined to be monotonically increasing from 15 H/m to 19 H/m. And the real part of permittivity ( ε ’) was fine-tuned by increasing temperature. As a result, at 920°C, μ ’ and ε ’ are closely equivalent ranging from 1 MHz to, this characteristics can be used for miniaturization and good radiation behaviors antennas. In addition, very low magnetic (tan δ μ ~3*10 −2 ) and dielectric (tan δ ε ~5*10 −3 ) tangent enable excellent radiation efficiency at operation.
