Chemical control on the size and properties of nano NiFe2O4 synthesized by sol–gel autocombustion method

Investigations of superparamagnetism in magnesium ferrite nano-sphere synthesized by ultrasonic spray pyrolysis technique for hyperthermia application

“…Obtained Curie temperature for all samples have shown in [51]. The Curie temperature decrease with the decrease of particle size showing a strong size effect which can be explained based on the molecular field of ferromagnetism theory [36]. According to this theory, magnetization decrease with increase temperature and at Curie temperature it becomes zero.…”

“…These results indicate a strong relationship between the crystallite size and pyrolysis temperature. This behavior can be attributed to an increase pyrolysis temperature which provides energy to the crystal growth [36]. In this case, liquid phase reaction mechanism have dominated.…”

Synthesis of Zno-Nife2o4 Magnetic Nanocomposites by Simple Solvothermal Method for Photocatalytic Dye Degradation Under Solar Light

“…The EDS spectra of NNi1 composition elements are shown in Fig. 2d [28][29][30] . Appearance superparamagnetic properties in nanocomposites …”

Dielectric and magnetic properties of Nickel ferrite ceramics using crystalline powders derived from DL alanine fuel in sol–gel auto-combustion

“…Nano-powders and ceramics of spinel ferrites find wide applications for magnetic recording media, magnetic memory devices, and as contrast agents in magnetic resonance imaging and magnetic drug delivery [1]. Nickel ferrite (NiFe 2 O 4 ) is one of the most important soft ferrites with unique properties, exhibiting high electromagnetic performance, low coercivity, good mechanical hardness and chemical stability.…”
