The effect of externally applied uniaxial compressive stress on the magnetic properties of power MnZn-ferrites

MnZn-ferrites: Targeted Material Design for New Emerging Application Products

“…As it has been repeatedly found in laboratory experiments, materials synthesized at this stoichiometric point possess the best stability of magnetic properties both as a function of time or as a function of some externally applied stress [9]. The explanation provided is that at this point the diffusion of cations (through cation vacancies) is limited.…”

The effect of hydrostatic stress on magnetic properties of Mn-Zn power ferrites at varying excitation levels

“…The loss increases are more profound at low excitation levels and the percentage decreases with the increase in the polarization. Measurements on a power ferrite at 100 mT show a loss increase in þ1:3% MPa À1 uniaxial at room temperature, 25 C. 18 The loss measurements under the hydrostatic pressure were carried out at room temperature (25 C); Figs. 6 and 7 show the change in power loss as a function of time under different excitation levels of 10, 20, and 30 mT of N87 and DMR95.…”

Effect of manganese doping on the magnetic and magnetocaloric properties of zinc ferrite

“…MnZn ferrites attracted considerable investigations because of their potential applications in catalysis, magnetic storage, cancer therapy, medical imaging and electronic devices. [1][2][3][4][5] The chemical processes currently in vogue for the synthesis of MnZn ferrite particles include co-precipitation, [6][7][8][9] the sol-gel auto-combustion method, [10][11][12][13] the solid-state reaction method, [14][15][16] solvothermal technique, [17][18][19] microwave processing technique, [20][21][22] hydrothermal synthesis etc. [23][24][25][26][27] The solvothermal technique has the advantages of functioning at low temperatures, being a simple, lowcost synthetic process, exhibiting an ease of compositional control and producing ultrafine particles with a narrow-sized distribution.…”
