Size effects on structural and magnetic properties of CoFe2O4 nanoparticles prepared by co-precipitation method

Effect of apple cider vinegar agent on the microstructure, phase evolution, and magnetic properties of CoFe2O4 magnetic nanoparticles

“…While, in the multi‐domain region, the coercivity increases with a decrease in the particle diameter. Therefore, there is a critical grain size at each temperature, which has been determined about 40‐44 nm for CFO MNPs at ambient temperature . So, the variation of H c with grain size is in good agreement with that reported by others.…”

Effect of Sm3+-Gd3+ co-doping on dielectric properties of Mn-Zn ferrites synthesized via combustion route

“…The effect of different rare earth ions substituted in ferrites already reported by several researchers. Rare earth ion substitution ferrites are synthesized by several physical and chemical methods such as chemical co precipitation method [6][7][8], solid state [9], hydrothermal synthesis [10], solution combustion route [11], sol-gel [12][13][14], sol-gel auto-combustion [15] microwave hydrothermal route [16,17]. However, most of all these methods are economically unfeasible.…”
