Investigations on Controlled‐Size‐Precipitated Cobalt Ferrite Nanoparticles
Source abstract
Abstract
Size‐dependent nanocrystalline cobalt ferrite (CoFe 2 O 4 ) particles have been synthesized by coprecipitation and investigated in detail. The effects of reducing the particle size on physical properties like crystalline phase, crystallite size, lattice strain, IR absorption, thermomagnetic measurements, and magnetization parameter are studied. Structural parameters in relevance to the shape and size of nanoparticles are discussed. The crystalline phase of cobalt ferrite remains stable down to 5 nm. Size‐dependent magnetization and the effect of surface area are presented. Characterization of samples has been performed using X‐ray diffractometer, transmission electron microscope, Fourier transform infrared spectrophotometer, vibrating sample magnetometer, and thermogravimetric analysis techniques.
