KAJIAN SIFAT KEMAGNETAN PADA NANOPARTIKEL COBALT FERRITE (CoFe2O4) YANG DIENKAPSULASI DENGAN POLYETHYLENE GLYKOL (PEG-4000) DAN SILIKA
Magnetic nanoparticles of Cobalt ferrite (CoFe2O4) have been succesfully encapsulated with various concentration of PEG-4000 and silica which used as materials for encapsulation. CoFe2O4 powder shynthesized by co-presipitation method. X-ray Diffraction (XRD) showed that after PEG-4000 encapsulated a...

description |
Magnetic nanoparticles of Cobalt ferrite (CoFe2O4) have been succesfully
encapsulated with various concentration of PEG-4000 and silica which used as
materials for encapsulation. CoFe2O4 powder shynthesized by co-presipitation
method. X-ray Diffraction (XRD) showed that after PEG-4000 encapsulated
appears new phases on CoFe2O4. It was which is
antiferromagnetic and which is paramagnetic. Both of phases was
decrease sample respons by eksternal field. Encapsulated of silica has showed the
new diffraction peaks, (222) and (331). Transmission Electron Microscopy (TEM)
analysis showed that encapsulated PEG-4000 and silica given decreasing
agglomeration, controlled shape of nanoparticles more spherical and dispersed.
Nanoparticle�s size and degree of crystallinity, increased with increasing
concentration of silica. Vibrating Sample Magnetometer VSM analysis show that
process of encapsulation by PEG-4000 and silica increasing coersivive field,
decreasing saturation and remanent magnetization |
