Size-induced effect on nano-crystalline CoFe2O4

Synthesis and characterisation of pure single-phase CoFe2O4 nanopowder via a simple aqueous solution-based EDTA-precursor route

“…[10][11][12]15,19] or comparable [13,[16][17][18] with other reported methods. Moreover, this method does not require any corrosive reagent like NaOH and any elaborate experimental setup.…”

“…We have reviewed several chemical synthesis methods used for the preparation of ferrites [8,9]. Synthesis routes are commonly used for CoFe 2 O 4 are co-precipitation [10][11][12][13][14], sol-gel [15,16], *Corresponding author. Email: naren70@yahoo.com precursors [17][18][19], reverse micelle [20], microemulsion [21], hydrothermal [22], etc.…”

A study on structural and magnetic properties of NixZn1-xFe2O4 (0 ≤ x ≤ 0.6) ferrite nanoparticles

“…The physical properties of these ferrite nanoparticles can be also tailored by changing the parameters such as composition or by the synthesis method. There are various methods for the synthesis of ferrite nanoparticles which includes sol-gel, oxidation, hydrothermal, ball milling and chemical coprecipitation method [8][9][10][11][12]. Out of these methods, sol-gel method is best method for the preparation of the nanoparticles because it maintains the stoichiometry of the starting components and prevents the presence of contamination and other impurities.…”

Induced Size Effects Of Gd3+ ions Doping On Structural And Magnetic Properties Of Ni-Zn Ferrite Nanoparticles

“…The g-value of raw samples is decreased from 2.04507 to 2. 00923 confirming the increase in particle size, with Gd 3+ ions concentration [15]. The increase in relaxation time with increase in Gd 3+ , may be due to the enhanced exchange bias interaction between ferromagnetic core and antiferromagnetic surface layer.…”

“…3). This increase is because of the larger ionic radii of the Gd 3+ (0.938 Å) ions as compared to Fe 3+ (0.6459 Å) ions occupying octahedral sites [15]. …”
