In this paper, the magnetic properties and heating capacity of cobalt ferrite (CoFe2O4) nanoparticles 13-24nm in size were studied and the specific absorption rate of the nanoparticles strongly depended on their magnetic properties.Abstract:
The magnetic properties and heating capacity of cobalt ferrite (CoFe2O4) nanoparticles 13–24 nm in size were studied. Results showed that the specific absorption rate of the nanoparticles strongly depended on their magnetic properties and particle size. Specific absorption rate values decreased with increased particle size, and the smallest CoFe2O4 nanoparticles (13.5 nm) exhibited the highest specific absorption rate. The mechanism underlying the decrease in specific absorption rate of the CoFe2O4 nanoparticles with increased particle size was also discussed.read more

The influence of synthesis parameters on one-step synthesized superparamagnetic cobalt ferrite nanoparticles with high saturation magnetization
TL;DR: In this article, superparamagnetic cobalt ferrite nanoparticles (SCFNs) were synthesized by co-precipitation in one-step and the synthesis parameters; reaction time and stirring rate, were varied separately while the other parameters were fixed constant to investigate the effect of the parameters on the properties of SCFNs.

Heating magnetic fluid with alternating magnetic field
TL;DR: In this paper, the authors developed analytical relationships and computations of power dissipation in magnetic fluid (ferrofluid) subjected to alternating magnetic field and showed that the dissipation results from the orientational relaxation of particles having thermal fluctuations in a viscous medium.
