Effect of titanium dioxide on microwave absorption properties of barium ferrite

A novel ternary hybrid electromagnetic wave-absorbing composite based on BaFe11.92(LaNd)0.04O19-titanium dioxide/multiwalled carbon nanotubes/polythiophene

“…The reasons for the decrease of magnetic parameters are as follows. Firstly, the introduction of the nonmagnetic polythiophene and MCNTs can hinder the grain continuity and result in the demagnetizing field [44]. Secondly, according to the equation of M S ¼ 4m S [45], M S is related to the volume fraction of the particles (4) and the saturation moment of a single particle (m S ).…”

Magnetic and dielectric properties of barium titanate-coated barium ferrite

“…In relative complex permittivity, the real part ε r symbolizes the storage capability of electric energy, and the imaginary part ε r demonstrates the loss of dielectric energy [9]. Fig.…”

“…Further technological applications require barium ferrite particles to be single magnetic domains and narrow particle size distribution [3,7]. Recently BaFe 12 O 19 were prepared using reverse microemulsion technique [8], sol-gel method [9] and coprecipitation method [5,10] and so forth. On the other hand, perovskite type structure barium titanate (BaTiO 3 ) is widely investigated concerning on the dielectric properties, phase transitions, grain size and dielectric relaxation.…”

Effects of High-Energy Ball Milling on the Microwave Absorption Properties of Sr0.9Nd0.1Fe12O19

“…Recent developments in microwave absorber technology have been focused on the materials with high wave absorption coefficient, good physical performance, and lower production cost [3,4]. There are a variety of absorber materials that can be used to suppress EMI depending on their suitability for low or high frequency applications [5][6][7]. According to the thickness and working frequency bandwidth, the magnetic composites have obvious advantages.…”
