Maghemite nanoparticles with very high AC-losses for application in RF-magnetic hyperthermia

An experimental study of the dynamic properties of nanoparticle colloids with identical magnetization but different particle size

“…[10] it is shown that the rate of magnetite formation depends on the pH value of the reacting medium, the concentration of reagents, the nature of the precipitator and the temperature of synthesis. [12]) and therefore it has not been of much commercially concern in manufacturing magnetic fluids, with respect to their saturation magnetization.…”

Role of polymeric surfactants on the growth of manganese ferrite nanoparticles

“…Magnetic nanoparticles have attracted great interests [1][2][3][4][5][6]. One of the most important groups of magnetic nanoparticles is ferrite which has a very high magnetization value at room temperature [7].…”

Synthesis and characterizations of water-based ferrofluids of substituted ferrites [Fe1−xBxFe2O4, B=Mn, Co (x=0–1)] for biomedical applications

“…SAR depends on several parameters like particles magnetization, size and distributions, AC magnetic field and frequencies [6]. Literature is available on the maximization of SAR of Fe 3 O 4 /g-Fe 2 O 3 particles where physical parameters like particles size and their distribution have been accounted and optimized [7]. However, besides the engineering of size and distribution of magnetic particle, SAR can be enhanced by choosing the magnetic particles of high magnetization at an applied AC magnetic field, since SAR has square dependency with magnetic moment (M).…”
