摘要:Two phase-based composites comprising barium titanate (BaTiO3) and spinel magnesium ferrite (1-x)
Mg0.7Cd0.3Fe2O4 +xBaTiO3 (x = 0.00, 0.03, 0.06, 0.09, and 0.12) were investigated. The phase structure
revealed the coexistence of the perovskite BaTiO3 and spinel MgFe2O4 phases. The microstructural analysis
indicated that the average crystallite size initially increased and then decreased, as the increase in x weakened
magnetisation, decreased saturation magnetisation (from 47.5 to 35.9 emu/g) and coercivity (150–0 Oe) were
obtained, resulting in reduced permeability at low frequency. The permittivity gradually increased owing to
tuning by barium titanate, which has strong dielectric properties, promising a relatively large miniaturisation
factor. Further, low magnetic loss (tan δμ ~10 2) and dielectric loss (tan δε ~ 10 2 to 10 3) guarantee high
quality factor. The low losses and enhanced dielectric properties of the as-synthesised composites could be
conducive to improving the behaviour of such magneto-dielectric composite systems in microwave applications.
