Ni0.4Cu0.2Zn0.4TbxFe2-xO4 nanospinel ferrites: Ultrasonic synthesis and physical properties

Synthesis and Characterizations of LaMnO3 Perovskite Powders Using Sol-Gel Method 

“…In Table 5, remanent magnetization (M r ) and coercivity (H c ) values of both powders were found to be approximately the same value, 0.1 emu/g and 82.95 Oe, respectively, despite them, saturation magnetization (M s ) value was obtained 0,96 emu/g for 500 o C and 1,69 emu/g for 850 o C. In spite of the α fact that the remanent magnetization (M r ) and coercivity (H c ) values are independent of the synthesis temperature, also an increase in synthesis temperature increases the permanent magnetization values of LaMnO 3 . In other words, the increase in the annealing temperature in the synthesis causes the magnetic properties to increase likewise [78][79][80][81]. Considering that all the properties of the powders we obtain are the same except the synthesis temperature and also the particle sizes.…”

Sonochemical catalysis as a unique strategy for the fabrication of nano-/micro-structured inorganics

“…Spinel ferrites are promising magnetic materials that are widely used in various fields, so lately, the sonochemical syntheses of novel spinel ferrite nanostructures have become an active research area. [74][75][76][77][78] For example, Almessiere, Slimani and coworkers produced a series of high-purity spinel ferrite compositions via the ultrasonic irradiation, such as [79][80][81][82][83][84][85][86][87][88][89][90][91][92][93] They examined the structural properties, morphological properties, and physical properties (e.g., magnetic traits, optical traits, and electrical traits) of products, and even evaluated their biological characterization for potential anti-cancer and anti-bacterial capabilities. Additionally, they also utilized ultrasonic-assisted approaches to prepare many ferromagnetic 19 (x = 0.00~0.05) hexaferrites, and so on.…”

Influence of size polydispersity on magnetic field tunable structures in magnetic nanofluids containing superparamagnetic nanoparticles

“…Among various magnetic nanomaterials such as ) nanoparticles are the widely used material in ferrofluids, owing to its high saturation magnetization, ease to synthesis, long term stability and superior bio-compatibility [1,2]. Fe 3 O 4 nanoparticles are prepared by various techniques such as coprecipitation [2], solvothermal decomposition [3], hydrothermal synthesis [4,5], sol-gel synthesis [6], microwave-assisted synthesis [7], sonochemical [8], ultrasonication [9], one-pot citrate sol-gel route, [10] etc. Composite Fe 3 O 4 nanoparticles have many applications in diverse fields such as magnetic resonance imaging contrast agents, cancer therapy, optical imaging, pathogen control, corrosion control and all-in-one devices [11][12][13][14][15].…”
