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

Role of Ce–Mn substitution on structural, electrical and magnetic properties of W-type strontium hexaferrites

“…Researchers attempted to substitute divalent and trivalent cations such as Cr [11], Co [12], La [13], Cu [14], Mg [15] etc. in W-type hexagonal ferrites to enhance their different properties.…”

“…Various techniques such as chemical co-precipitation [11], stearic acid gel [12], standard ceramic [15], citrate combustion [19] sol-gel [21] and hydrothermal method [22] have been used for the synthesis of W-type hexagonal ferrites. Amongst these different techniques chemical co-precipitation method is found to be very suitable because of its simplicity, lower cost, comparatively lower annealing temperature and annealing time to achieve the pure single phase.…”

Structural and magnetic properties of BaCo2-xNixFe16O27 hexagonal ferrite prepared by a simple heat treatment method

“…Substitution of divalent or trivalent ions among various sublattices of hexagonal lattice can be used to improve intrinsic magnetic properties of barium hexaferrites [7]. During last decade various efforts have been made to improve structural and magnetic properties of barium hexaferrites by divalent and trivalent substitutions [8][9][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].…”
