Structural and magnetic properties of Dy3+ doped Y3Fe5O12 for microwave devices

Conventional and Microwave Hydrothermal Synthesis and Application of Functional Materials: A Review

“…The obtained powder has high crystallinity and no obvious agglomeration and shows high reactivity. Sadhana et al [125] prepared Dy 3+ doped Y 3−x Dy x Fe 5 O 12 (x = 0–3) nanopowders using the microwave hydrothermal method. The microwave treatment was conducted at 200 °C for 45 min with a power of 600 W. Compared to the common hydrothermal method, the microwave temperature method can significantly decrease the reaction temperature and time.…”

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.…”

Influence of Temperature on Structural and Magnetic Properties of Gd3AlxFe5−xO12 (x = 2)

“…[27] Hydrothermal technique is also become one of the interests of many researchers as this method provide very high speed of heating with good reaction kinetics which give high yield. [28] Another promising method is the sol-gel method [13,15] which provide better homogeneity in garnet phase because of rate of mixing, but due to larger time require to dry the gel limit this method. [29] In addition to this method, the sol-gel autocombustion method provides superiority because it solves the problem of drying gel [30,31] by adding fuel like citric acid in precursor the dried gel turned into powder by autoignition.…”
