The Magnetic Anisotropy Effectiveness on NiFe2O4 and NiFe2O4@SiO2 Nanoparticles for Hyperthermia Applications
Journal Title: Cumhuriyet Science journal - Year 2017, Vol 38, Issue 4
Abstract
In this study, we analyzed the magneto-heating properties of NiFe2O4 nanoparticles, coated with a SiO2 shell for hyperthermia applications. The NiFe2O4 nanoparticles were synthesized and coated with SiO2 by chemical route and water in oil techniques, respectively. The size of core particles is ~5.6±0.1 nm and the thicknesses of the SiO2 layers around the core change from 0 nm to 14.1±0.1 nm by increasing the amount of tetraethyl orthosilicate from 0 ml to 2.5 mL during the synthesis process. The magnetic anisotropies, obtained from magnetic susceptibility measurements have the same behavior with the specific heat absorption ratio of the samples.
