The role of Mg substitution on the microstructure and magnetic properties of Ba Co Zn W-type hexagonal ferrites

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

“…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]. found that ε' and tan ı decrease by exceeding frequency above the relaxation value and by decreasing the temperature [11].…”

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.…”

Effects of Divalent Ion Substitution on the Microstructure and Magnetic Properties of SrCo 2−x (MnZnCa) x/3Fe 1 6 O 2 7 Nanoparticles

“…Various techniques such as chemical co-precipitation [9,10], sol-gel [11,12], standard ceramic [13,14], microemulsion, and reverse micelle [15] were employed for the synthesis of hexaferrites. Among these different techniques, chemical co-precipitation method is found to be very suitable because of its simplicity, lower cost, and comparatively lower annealing temperature and annealing time to achieve the pure single phase.…”
