A review on MnZn ferrites: Synthesis, characterization and applications

“…In this method toxic and expensive organic solvents are not used in the reaction and all the materials used to synthesize MnZn nanoparticles are easily available and cost effective. The synthesis process is performed at room temperature under atmospheric pressure which is facile and economic.Many researchers synthesized MnZn ferrites by using this method [30,132,134,190]. The raw materials MnCO 3 , ZnO and Fe 2 O 3 in the proper weight were powdered and the powdered samples were calcined at 1100℃ for 5h in air atmosphere using muffle furnace with heating rate of 10℃/min and a cooling rate of 5℃/min.…”

“…In this paper, high permeability of MnZn ferrites was reduced by increasingthe energy consumption in the synthesis reaction due to prolonged sintering process for the production of nanoferrites. Zapata et al [30] studied effect of zinc concentration on the microstructure and relaxation frequency of Mn-Zn ferrites synthesized by solid state reaction. Rahaman et al [193] studied synthesis, structural, and electromagnetic properties of Mg doped ferrites.…”

“…On the other hand, soft ferrites have low coercivity as a result of which their magnetization can easily be altered. Soft ferries are good conductors of magnetic field which has led to its wide range of applications in electronic industry such as developing transformer cores, high frequency inductors and as microwave components [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42], see figure 1 for more details. Furthermore, advantages of soft ferrites include high resistivity, low cost, time and temperature stability, low loss and high permeability [43][44][45][46].…”

Synthesis of a low loss Mn–Zn ferrite for power applications

“…A known consequence of the increased Zn content is the shift of the Curie temperature towards lower temperatures [14], as well as the shift of the secondary permeability maximum also towards lower temperatures. Moreover, the increase of the Zn content influences the anisotropy of the Mn-Zn ferrite and the point where the K 1 constant crosses zero is shifted to a lower temperature [15].…”
