Synthesis of nanocrystalline Ba(CoxZn1−x)2Fe16O27 by sol–gel auto-combustion method

Enhancement of electrical and dielectric properties of Cr doped BaZn2 W-type hexaferrite for potential applications in high frequency devices

“…Their specific electrical and magnetic properties depend on impurities, particle size, lattice structure and crystallographic defects. O 27 has also been reported [9]. The doping of BaCoZnFe 16 O 27 with low concentration of Mg shows considerable improvement in its magnetic properties [10].…”

Influence of Nd3+ substitution on the microstructure and electromagnetic properties of barium W-type hexaferrite

“…It is reported that ions substitution may improve their properties and characteristics. The main issue concerning the ions substitution of the Fe 3+ , Co 2+ and/or Ba 2+ ions in the structure to change the magnetic properties, microstructures and absorbing performance of hexaferrites has been reported in many literatures [7][8][9][10][11]. Rare-earth elements (RE) have typical relaxation characteristics, which can affect the electromagnetic properties of ferrite magically [12].…”
