“…The higher the annealing temperature, the higher is magnetization saturation: 36, 63, and 78 emu g -1 for 400 °C, 850 °C and 1000 °C annealing temperature, respectively. Furthermore, the remanence to magnetization saturation ratio is 0.6 for particles annealed at 850 °C, indicating randomly oriented equiaxial crystallites with cubic magnetocrystalline anisotropy in the system [14]. On the other hand, the lower the annealing temperature used, the higher the coercivity, i.e.…”

Magnetic nanoparticles of spinel nanocrystalline cobalt ferrite were synthesized via the solgel method and subsequent annealing. The influence of the annealing temperature on the structure, magnetic properties, and magnetorheological effect was investigated. The finite crystallite size of particles determined by X-ray diffraction as well as particle size observed via transmission electron microscopy increased with annealing temperature. The magnetic properties observed via vibrating sample magnetometer showed that an increase in the annealing temperature leads to the increase in the magnetization saturation and, in contrast, a decrease in coercivity. The effect of annealing on magnetic properties of ferrite particles has been explained by the recrystallization process at high temperature resulting in grain size growth and decrease in an imposed stress relating to defects of crystal lattice structure of nanoparticles. The magnetorheological characteristics of suspensions of ferrite particles in silicone oil were measured using a rotational rheometer equipped with a magnetic field generator in both steady shear and small-strain oscillatory regime. The magnetorheological performance expressed as a relative increase in magnetoviscosity appeared to be significantly higher for suspensions of particles annealed at 1000 C.

“…Surfactants, nanoparticles, nanomagnetizable or coating magnetizable particles can be added to reduce the sedimentation of the heavy particles in the liquid phase [14,13]. The sedimentation phenomenon can cause a shear-thinning behaviour of the suspension [15].…”
